Question

Given mn, find the value of x.
(7x+14)⁰
(9x-8)°

Answer 1

x = 11

Explanation:

Since the two lines are parallel, the marked angles are equal to each other.

7x + 14 = 9x - 8

Subtract 7x.

14 = 2x - 8

Add 8

22 = 2x

Divide by 2.

11 = x

x = 11

Answer 2

x = 11

Explanation:

7x + 14 = 9x - 8 [ Corresponding angles]

=> 7x - 9x = - 8 - 14

=> -2x = -22

=> x = 11
