Question

find the measure of an angle if 3 times its supplement is 60 degree more than 6 times its complement

Answer 1

Hi...

let the angle be x

3(180-x)=6(90-x)+60

540-3x=540-6x+60

-3x+6x=60

3x=60

x=20

Angle=20°

Answer 2

Answer:

3(180-x) = 6(90-x) + 60

=> 540 - 3x = 540 - 6x + 60

=> 6x - 3x = 60

=> 3x = 60

=> x = 60/3

=> x = 20

So the angle is 20
