find the measure of an angle if its measure is q5 more than 2 times its supplement

Answer 1

Let x = measure of the angle

then (180-x) be the supplement of the angle

and from: "the measure of an angle its measure is 15 more than two times its supplement" we get:

x = 15+ 2(180-x)

x = 15+ 360 - 2x (Distribution)

x=375-2x (add 2x to each side)

3x=375 (divide by 3)

x= 125 degrees
