Question

7) ABCD is a quadrilateral with angle A = angle C and
angle B = angle D. If angle A is twice angle b, find the measure
of each angle.​

Answer 1

Answer:

angle are the twice of two times then angle B

Answer 2

Answer:

A=C

let a and c be x

x=x

B=D(2times of a)

So, b=2x

2x=2x

Therefore, x+x+2x+2x=360°

6x=360°

x=360/6

x=60°

So, the measure of each angle is 60°
