How do special right triangles theorems 45 45 90 and 30 60 90 differ from each other?.

Answers

Answer 1

The 45-45-90 triangle has two congruent sides and one right angle, with each angle measuring 45°. The sides are perpendicular to each other and the length of the hypotenuse is equal to the square root of 2 times the length of a leg.

The 30-60-90 triangle has one right angle and two sides that are proportional. The shortest side is half the length of the hypotenuse and the middle side is equal to the shortest side times the square root of 3. The two acute angles in the triangle measure 30° and 60°, respectively.

In conclusion, both 45-45-90 and 30-60-90 triangles are special right triangles with distinct relationships between their sides and angles.

A triangle is a polygon with three edges and 3 vertices. The terminology for categorizing triangles is more than two thousand years vintage, having been defined on the first actual page of Euclid's elements.

In Euclidean geometry, any three factors, while non-collinear, decide a completely unique triangle and simultaneously, a unique plane (i.e. a -dimensional Euclidean space). In different words, there's best one plane that consists of that triangle, and every triangle is contained in some plane. If the entire geometry is only the Euclidean plane, there is the best one plane and all triangles are contained in it; however, in higher-dimensional Euclidean spaces, this is not real. this text is ready triangles in Euclidean geometry, and in particular, the Euclidean plane, except wherein otherwise stated.

Answers

Jamal and Lin will meet 3.21 miles from Jamal's house.

What is meet?

Meet is a gathering of two or more people for a specific purpose, such as to discuss an issue, make a decision, or socialize. It can take place in person or online, either in a formal or informal setting.

The time it takes for Jamal and Lin to meet is the time it takes for Jamal to travel 2 miles plus the time it takes for Lin to travel 2 miles.
Since Jamal is walking at 3 mi/h, it takes him (2 miles) / (3 mi/h) = 0.67 hours to travel 2 miles.
Since Lin is walking at 5 mi/h, it takes her (2 miles) / (5 mi/h) = 0.4 hours to travel 2 miles.
The total time it takes for Jamal and Lin to meet is 0.67 + 0.4 = 1.07 hours.
Jamal and Lin will meet 1.07 hours after they left their houses.
Since Jamal is walking at 3 mi/h, he will have traveled (1.07 hours) * (3 mi/h) = 3.21 miles when they meet.

Answers

The measure of the exterior angle in this case is 60+60 = 120 degrees.

What is exterior angle ?

An exterior angle of a polygon is an angle formed between one side of the polygon and a line extended from the endpoint of the opposite side. An exterior angle can be formed by standing outside of the polygon and looking at it.

In a triangle, the measure of an exterior angle is equal to the sum of the measures of the two interior angles opposite to it. In any convex polygon, the sum of the measures of the exterior angles is always 360 degrees.

The support for a window air-conditioning unit forms a triangle. A triangle is a three-sided polygon, and all the interior angles in a triangle add up to 180 degrees. Therefore, the measure of each interior angle of a triangle is (180/3) = 60 degrees.

Answers

The height of the statue is:

A. 276 inches

If Wally, who is 69 inches tall, catch a shadow that is 41 inch in length.

Height of Statue Calculation

To determine the height of the statue, you can use the principle of similar triangles. Similar triangles have the same angles, but not necessarily the same side lengths. You can use the ratio of the height of Wally and the length of his shadow to the height of the statue and the length of its shadow to find the height of the statue.

Height of Wally: 69 inches

Length of Wally's shadow: 41 inches

Height of statue: x

Length of statue's shadow: 164 inches

You can set up the proportion as:

69/41 = x/164

Solving for x, you get:

x = (69 × 164)/41

x = 276 inches

k is a non-zero whole number. Given that 15 x 375 x k is a perfect cube, write down the smallest value of k.​

Answers

Answer:

k = 75

Step-by-step explanation:

Let's write down the prime factors of 15 and 375

15 = 3 x 5

375 = 3 x 5 x 5 x 5

So 15 x 375 = 3 x 5 x 3 x 5 x 5 x 5

= (3 x 3) x   (5 x 5 x 5) x 5

This cannot be a perfect cube

However if we multiply this by 3 x 5 x 5 we will get

(3 x 3 x ) x (5 x 5 x 5) x(5 x 5 x 5) which is a perfect cube

Since we are asked to find k such that 15 x 375 x k is a perfect cube

k = 3 x 5 x 5 = 75

k = 75

k = 75

find the value of x in each supplementary angle pair

Answers

Answer:

x = 14°

Step-by-step explanation:

We know that,

→ Straight line is always 180°.

Forming the equation,

→ 156° + (x + 10°) = 180°

Now the value of x will be,

→ 156° + (x + 10°) = 180°

→ x + 166° = 180°

→ x = 180° - 166°

→ [ x = 14° ]

Hence, the value of x is 14°.

The value of x in the given supplementary angle pair is 14°.

Explain the term supplementary angle?Angles that add up to 180 degrees are referred to as supplementary angles. For instance, angle 130° as well as angle 50° are complementary angles since the sum of these two angles is 180°.Two angles are classified as supplementary angles because they combine to generate a linear angle when their sum is 180 degrees. When two angles add up to 90 degrees, however, they are thought to be complimentary angles and together they make a right angle.

Then,

156 + (x + 10) = 180

166 + x = 180

x = 180 - 166

x = 14°

Thus, the value of x in the given supplementary angle pair is 14°.

At a Mexican retaurant, you order a taco for $1. 85 and burrito dinner for $7. 35. Sale tax i 7. 5% and you leave a tip of 15%. What i your total bill including tip and tax?

Answers

So, your total bill including tip and tax is $11.37

First, calculate the subtotal of the food bill by adding the cost of the taco and burrito dinner:

$1.85 + $7.35 = $9.20

Next, calculate the sales tax by multiplying the subtotal by the tax rate (7.5%):

$9.20 x 0.075 = $0.69

Then add the sales tax to the subtotal to get the total before tip:

$9.20 + $0.69 = $9.89

Then calculate the tip by multiplying the total before tip by the tip rate (15%):

$9.89 x 0.15 = $1.48

Finally, add the tip to the total before tip to get the final total bill including tip and tax:

$9.89 + $1.48 = $11.37

The "old London" mile, which was eight furlongs, was first established around the year 1500. The mile at that time was equal to 5,000 feet, with the furlong being 625 feet at that time, using the larger northern (German) foot.

A statute from 1593 that confirmed the use of a shorter foot and made the length of the furlong 660 feet increased the mile by 280 feet during the reign of Queen Elizabeth I, bringing it to 5,280 feet.

The Fewer mile he ran = (16 × 14) - (3 × 10)

                                      = 194 miles

Thus, He ran 194 miles fewer he ran in 3 days than the 16 days run.

How do you find the equation of the axis of symmetry using factored form?.

Answers

To find the equation of the axis of symmetry using factored form, we can use the multiply and conversion method which converts it into vertex form.

It can be multiplied and converted to vertex form.

Example: (x-3)(x+2) f(x)

f(x) = x^2 - x - 6

We can now combine the x terms to finish the square.

f(x) = (x^2 - x +1/4 ) - 6 - 1/4

f(x)= (x - 1/2)^2 -25/4

As a result, the vertex is (1/2, -25/4)

Any quadratic given in factored form can be solved this way.

If the parabola contains the equation y=f(x)=a(xr1)(xr2), the zeroes of f(x), i.e., r1 and r2, can be read off right away. The vertex then has coordinates (h,k), where k=f(h) is the result of inserting x=h through the function f(x), and h=(r1+r2)/2 is the average of the two zeroes.
