Question

An angle is 25 percent more than its supplement. Find the measure of the angle.

Answer 1

Step-by-step explanation:

The supplement of an angle is 180° less than itself

Let us consider an angle is x . Then it's supplement is 180-x

According to the question,

x+25% of x =180-x

25% of x is 1/4th of x

So,x+1/4x=180-x

By solving this equation we get x is 100°
