Find the measure of an angle , if seven times its complement is 10 degree less than three times

Answer»

Hey

Here is your answer,

LET the ANGLE be x
measure of its COMPLEMENT = (90-x)
measure of its supplement= (180-x)
7(90-x) =3(180-x)-10
630 - 7x=540x-3x -10
-7x+3x= 530-630
-4x=-100
x= 100/4
x=25

Hope it HELPS you!
