Question

An angle measures 76° . what is the measure of its supplement​

Answer 1

The answer is

104°

Explanation:

Let the measure of it's supplement be x

Supplementary angles sum up to 180° which means the sum of 76° and it's supplement is 180°

To find its supplement add 76° and it's supplement and equate it to 180° to find x

So we have

76 + x = 180

x = 180 - 76

We have the final answer as

x = 104°
