Question

Two angles are supplementary. The measure of one angle is 6 less than 20% of the other. Find the measure of both angles

Answer 1

Answer:

let one angle be x and other be y

y=0.2x-6

since both are supplements so sum will be 360

x+y=360

x+.2x-6=360

1.2x=366

x=3660/12=305

y=55

one angle will be =305

second angle =55
