Question

Given mn, find the value of x.
(10X-14)
(7x-8)°

Answer 1

x=2

Explanation:

The angles are corresponding angles and corresponding angles are equal when the lines are parallel.

10x-14 = 7x-8

Subtract 7x from each side

10x-14-7x = 7x-8-7x

3x-14 = -8

Add 14 to each side

3x-14+14 = -8+14

3x = 6

Divide by 3

3x/3 = 6/3

x=2
