Answer:
a = 97° , b = 19°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
(a)
a is an exterior angle of the triangle , then
a = 40° + 57° = 97°
(b)
57° is an exterior angle of the triangle , then
b + 38° = 57° ( subtract 38° from both sides )
b = 19°

How do you find the length of the third side of an acute triangle?.
There are several ways to find the length of the third side of an acute triangle, depending on the information given about the triangle and the sides. Some common methods include:
Using the Pythagorean theorem: If you have a right triangle, you can use the Pythagorean theorem to find the length of the third side. The theorem states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Using the Law of Cosines: If you know the lengths of two sides and the measure of the angle between them, you can use the law of cosines to find the length of the third side.
Using the Law of Sines: If you know the lengths of two sides and the measure of the angle opposite one of them, you can use the law of sines to find the length of the third side.
It's important to note that you need to know at least 2 sides and an angle or the side opposite to the right angle (if the triangle is a right triangle) in order to find the length of the third side.

Use the distributive property to write an expression that is equivalent to . 6−9x
The distributive property states that for any real numbers a, b and c, the following is true:
a(b + c) = ab + ac
To use the distributive property to write an expression that is equivalent to 6 - 9x, we can factor out the -9x from the second term:
6 - 9x = 6 - 9x + 0 - 0x = 6 - 9x + (-9x) = 6 + (-9x)
Therefore, using the distributive property, we can write an expression that is equivalent to 6 - 9x as:

Answer:
slope = 1
Step-by-step explanation:
calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (3, 2) ← 2 ordered pairs from the table
m = [tex]\frac{2-(-1)}{3-0}[/tex] = [tex]\frac{2+1}{3}[/tex] = [tex]\frac{3}{3}[/tex] = 1
How do you graph y <- 2x 4?.
To depict the curve, we will make use of the idea of slope and intercept in linear equations.
A line's slope and y-intercept are represented by the equation y = mx + c, where m represents the slope and c represents the y-intercept.
When y = 2x - 4 is put into comparison with the generic form, we get
The curve has a slope of 2 and a y-intercept of -4.
To assist us plot the graph, let's take two points along the line y = 2x – 4.
The line y = 2x - 4 passes through since its y-intercept is equal to -4. (0, -4)
In the formula y = 2x - 4, replace y with 0.
0 = 2x - 4
2x = 4
x = 2
the line therefore goes through (2, 0).

What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, A storage silo for grain can house 18,000 bushels of grain.
1. One bushel of oats weighs 32 pounds which is equal to 32/2000 tons.

If 10 people share 3 brownies equally, each person will get the same amount. To find out how much each person will get, you can divide the total number of brownies by the number of people.
Unitary Method:
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
3 brownies / 10 people = 0.3 brownies per person
So, each person will get 0.3 of a brownie. Since a brownie is a solid object, it is not possible for each person to get 0.3 of a brownie, It would be best to cut the brownies into 10 equal pieces.

Complete the ratio table.
145 52
290 104
435 156
580
725
Step-by-step explanation:
since a ratio is a fraction with all calculation and comparison rules (but with a special overall meaning), we need to observe the main rule for transforming fractions : when multiplying one part of the fraction by a factor, we also need to multiply the other part by the same factor to keep the value of the fraction unchanged.
the basic ratio is here
145/52 (or written 145:52 - it has the same meaning)
290/104 is just (145×2)/(52×2)
435/156 is just (145×3)/(52×3)
to complete the table we simply have to keep following that structure :
580 = 145×4
so, 52×4 = 208
and the ratio is
580/208
725 = 145×5
52×5 = 260
and the ratio is
725/260

What kind of triangle is this 90 29 61?.
The triangle with angles of 90 degrees, 29 degrees, and 61 degrees is a general right triangle that does not belong to any specific type of triangle and it has no specific ratios between the sides.
The triangle with angles of 90 degrees, 29 degrees, and 61 degrees is not a special type of triangle. It is a general right triangle because it has one right angle (90 degrees) and two acute angles (29 degrees and 61 degrees).
This triangle is not a 30-60-90 triangle because it does not have the specific angle measurements of 30-60-90 degrees. Similarly, it's not a 45-45-90 triangle because the angles don't match the specific angles of 45-45-90 degrees. There are no specific ratios between the sides of this triangle.
In general, right triangles are triangles that have one right angle (90 degrees), and the other two angles can take any value between 0 and 90 degrees. The sides of a right triangle have a relationship known as the Pythagorean Theorem. This theorem states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
Therefore, In short, the triangle with angles of 90 degrees, 29 degrees, and 61 degrees is a general right triangle that does not belong to any specific type of triangle and it has no specific ratios between the sides.

If a: b = 1:2 and b; c = 3:4, find a : c.
Answer:
Step-by-step explanation:
b:c= 3:6
Answer:
Step-by-step explanation:
We know that:
a : b = 1 : 2 (or a = (1/b)*b)
b : c = 3 : 4 (or b = (3/4)*c)
So, we can substitute the value of b from the second equation into the first equation to get the ratio of a : c:
a = (1/b)*b = (1/((3/4)c))((3/4)c) = (4/3)(1/c)*c = (4/3)*1 = 4/3
So, the ratio of a : c is 4 : 3.
Alternatively, we can use the cross-multiplication method to find the ratio.
a : b = 1 : 2, and b : c = 3 : 4
so a4 = b3, and b4 = c3
so a4 = c3
so a:c = 3:4
In this way also we got the ratio of a:c as 3:4

how much work is done when a 100 lb rock is lifted to a height of 3 ft?
Work done when a 100 lb rock is lifted to height of 3 ft is 9652.215 ft-lb.
What is meant by work done?
The work done on an object is equal to the force applied to it multiplied by the distance over which the force is applied. In this case, the force applied is the weight of the rock, which is equal to the force of gravity acting on it.
The weight of an object is given by the formula:
W = mg
Where m is the mass of the object (in this case, 100 lb) and g is the acceleration due to gravity (approximately 9.8 m/s^2 or 32.17405 ft/s^2).
So the weight of the rock is:
W = (100 lb)(32.17405 ft/s^2) = 3,217.405 ft-lb
The work done on the rock is equal to the force applied (its weight) multiplied by the distance it is lifted (3 ft), so the work done is:
Work = (3,217.405 ft-lb) x (3 ft) = 9652.215 ft-lb
Therefore, the work done when a 100 lb rock is lifted to a height of 3 ft is 9652.215 ft-lb.
