Question

Given ABCD, solve for x.

Answer 1

X value is 9 degree.

Answer 2

x=9

Explanation:

Given is a parallelogram ABCD

AB and CD are parallel sides and also BC with AD

Since AB and CD are parallel we have

angle A + angle D =180

Angle A = 30+5x and angle B =15+10x

Sum = 30+5x+15+10x = 180

Simplify to get

45+15x =180

Subtract 45

15x = 180-45 =135

Divide by 15

x=9
