The measure of an angles supplement is 76 less than the measure of the angle. find the measure of the angle and it’s supplement.

Hello!

A supplement is another angle that, with the given angle, add up to 180. This gives us the equation below.

a+a-76=180

Let's combine like terms.

2a-76=180

We add 76 to both sides.

2a=256

We divide both sides by 2

a=128

This means our one angle is 128. We subtract 78 from it to find its supplement.

128-76=42

Therefore, our angle is 128°, and its supplement is 42°.

I hope this helps!

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
