Answer:

x=8

Explanation:

Given

AB||CD

$\angle ABC = 5x + 50$

$\angle BCD = 7x + 34$

Required

Find x

If
AB||CD i.e. If AB is parallel to CD, then

$\angle ABC = \angle BCD$

Substitute values for ABC and BCD

5x + 50 = 7x + 34

Collect Like Terms

5x - 7x = -50 + 34

-2x = -16

Multiply through by
-(1)/(2)

-(1)/(2) * -2x = -16 * -(1)/(2)

(1)/(2) * 2x = 16 * (1)/(2)

(2x)/(2) = (16)/(2)

x = (16)/(2)

x=8
