Question

Can u pls help me !!!!!!!

Answer 1

Answer:

45° and 135°

Step-by-step explanation:

angle A = 3 × angle B

angle A + angle B = 180°.....(adj. angles in a ||gm are supplementary)

3 angle B + angle B = 180°

4 angle B = 180°

angle B = 45°

angle A = 3×45° = 135°

angle A = angle C and angle B = angle D (opp. angles in a ||gm are equal)

angle C = 135° and angle D = 45°
