Question

Q13. In parallelogram ABCD, ZA = (5x - 20) and ZC = (3x + 40°. Find the value of x.

​

Answer 1

Opposite sides of a parallelogram are equal, therefore
(5x-20) = (3x+40)
5x - 3x = 40+ 20
2x = 60
x= 30
Thanks

Answer 2

Step-by-step explanation:

ABCD is a parallelogram

We know that

Opposite Angle of the Parallelogram are Equal

∠A = ∠C

5x - 20° = 3x + 40°

2x = 60°

x = 30°

Hence ,The value of x is 30°
