Question

angle A and angle B are interior angles if angle a = x and angle B = 3 x find angle a and b​

Answer 1

Answer:

A=45°

B=135°

Step-by-step explanation:

∠A + ∠B= 180° interior angles are supplementary

x + 3x =180

4x =180

x= 180/4

x= 45°

A=45°

B=3×45 = 135°

Answer 2

Answer:

Measure of interior Angles = 180

x + 3x = 180

4x = 180

x = 180÷4

Angle A = x = 45

therefore Angle B = 3×45

Angle B = 135
