Question

In a parallelogram ABCD, A is double of B. Find all the angles of the parallelogram?Help plz​

Answer 1

Answer:

Step-by-step explanation:let x be the b angle

so angle a = 2x

angle A = angle C ( opposite angles are equal)

angle B = angle D

so 2x+x+2x+x=360°

6x=360°

x = 60°

so angle B and D = 60°

and angle A and C = 120°

Answer 2

Answer:

A+B+C+D=360

2B+C+D=360

Opposite angles are equal

B=C

A =D

2B+B+2B=360

B=72
