hurry please! 20 points. Find the measure of angle θ. Round your answer to the nearest tenth place.
Answers
Answer:
Angle θ would be about 17.1 degrees.
Step-by-step explanation:
To figure out what Angle θ is, first we have to find the hypotenuse. You can easily do that by find the square root of BC² + AC².
c = √4² + 13²
Square 4 and 13 to get 16 and 169 respectively.
c = √16 + 169
Add 16 and 169 to get 185.
c = √185
Find the square root of 185 (I'll round to the nearest tenth.)
c = 13.60147 ≈ 13.6 units
To find angle β, divide AC by AB and find the inverse sine of that.
β = arcsin(13/13.6)
Divide 13 by 13.6. Round to the nearest thousandth.
β = arcsin(0.955)
β ≈ 1.2723 rad
To convert radians to degrees, multiply the radians by 57.2957795 for an approximate amount.
β ≈ (1.2723 * 57.2957795)°
β ≈ 72.8974203 ≈ 72.9 degrees
Now subtract 72.9 from 90 to get angle θ's measure of 17.1 degrees.

20% of the girls in class have blonde hair. 16 girls do not have blonde hair. How many total students
Answers
Since 7 have blonde hair and 9 have glasses, that would be a total of 16 persons if there were no overlap; that is, no blonde wears glasses and nobody who wears glasses is a blonde.
But there are 4 persons who have both blond hair and wears glasses. That means, of the 7 who are blondes, 3 of them do not wear glasses. And, of the 9 who wear glasses, 5 of them are not blondes.
So we have 3 who are blondes without glasses, 5 who wear glasses who are not blondes, and 4 blonds with glasses, for a total of 12 persons.
The probability is, therefore, 12/26 or 6/13.

What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is an expression as -
5 - 3(x + 1) = 2y - 3x + 2
The given expression is -
5 - 3(x + 1) = 2y - 3x + 2
5 - 3x - 3 = 2y - 3x + 2
2 - 3x = 2y - 3x + 2
2 - 3x + 3x - 2 = 2y
2y = 0
y = 0
y = 0x + 0
Therefore, we can write the given equation in the form of y = mx + b as -
y = 0x + 0.

[tex]Height = 40[/tex]
Step-by-step explanation:
Given
Shape: Triangle
[tex]Area = 10cm^2[/tex]
[tex]Base = \frac{1}{2}cm[/tex]
Required
Determine the height
Area of a triangle is calculated as:
[tex]Area = \frac{1}{2} * Base * Height[/tex]
Substitute values for Area and Base
[tex]10= \frac{1}{2} * \frac{1}{2}* Height[/tex]
[tex]10= \frac{1}{4}* Height[/tex]
Multiply both sides by 4
[tex]4 * 10= 4 * \frac{1}{4}* Height[/tex]
[tex]4 * 10= Height[/tex]
[tex]40= Height[/tex]
[tex]Height = 40[/tex]
Hence, the height is 40cm

There are 4 colors of Starburst flavors: yellow, pink, red, and orange. If the probability of getting an orange is 2 5 2 5 , yellow is 1 10 1 10 , and the probability of getting red is 3 10 3 10 , what is the probability of getting pink?
Answers
Answer: 1/5
Step-by-step explanation:
From the question, we are informed that there are 4 colors of Starburst flavors: yellow, pink, red, and orange. We are further told that the probability of getting an orange is 2/5, yellow is 1/10 , and red is 3/10.
The probability of getting pink would be:
= 1 - [P(orange) + P(yellow) + P(red)]
= 1 - (2/5 + 1/10 + 3/10)
= 1 - (4/10 + 1/10 + 3/10)
= 1 - 8/10
= 2/10
= 1/5

Answer:
An obtuse triangle has one angle larger than 90 degrees (deg). Given information, the two base angles EDF and EFD are represented by one variable x, therefore they are equal.
The sum of all angles of any triangle is 180 deg so angles EDF + EFD + DEF = 180 deg
Since the obtuse angle must be larger than 90 deg, the sum of the other two angles must be less than 90.
Angles EDF + EFD < 90 and 90 < DEF can be re written
An inequality of angles EDF + EFD < DEF
Since angles EDF and EFD are equal to x their sum is (x + x) or 2x, so we can write
2x < 90 divide both sides by 2
{0 < x < 45} is all possible values of x.
A function can be written to represent this. The function will accept input of the obtuse angle and output the two equal acute angles.
F(x) = (180 - x) / 2
where x is the measure of the obtuse angle. Only works for symmetric triangle. F(x) is the measure of each of the other two angles.

We work with the ratio
Total ratio is:
1 + 2 + 3 = 6

When a rocket is launched, it climbs 50 feet for every 13 feet it travels horizontally. Estimate the rocket's distance (Find the missing side of triangle).
Answers
Answer:
i don t this topic because i am the secundary
Step-by-step explanation:
.
The value of rocket's distance will be 51.66.
What is Pythagoras theorem?
The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.
Given that;
When a rocket is launched, it climbs 50 feet for every 13 feet it travels horizontally.
Now,
Since, When a rocket is launched, it climbs 50 feet for every 13 feet it travels horizontally.
And, The figure is shown the right triangle.
So, We can apply the Pythagoras theorem as;
⇒ x² = 50² + 13²
⇒ x² = 2500 + 169
⇒ x² = 2669
⇒ x = √2669
⇒ x = 51.66
Thus, The value of rocket's distance will be 51.66.
