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:
A+B+C+D=360
2B+C+D=360
Opposite angles are equal
B=C
A =D
2B+B+2B=360
B=72
