Angle A and angle B complement each other, and angle a is 30 degrees larger than half of angle B. calculate the degree of angle A and angle B

Angle A and angle B complement each other, and angle a is 30 degrees larger than half of angle B. calculate the degree of angle A and angle B

Let B = X
Then the angle a = 180-x
therefore
180-x=1/2x+30
1.5x=150
x=100
Angle a is 80 degrees and angle B is 100 degrees
