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!

a negative exponent is translated as follows:

so, we have

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
