Question

If two angles are supplementary (sum of the two angles equals 180 degrees), find each angle if one angle is 30 degrees more than twice the other angle.

Answer 1

A/q
Let angle A be x
Then angle B is 2x+30°
Angle A+ angle B =180°[given}
X+2x+30=180°
3x=180-30
x=150÷3
x=50
Angle A =50°
Angle B =130
