Question

Given m || n, find the value of x.
m
(2x-13)°
n
123°

Answer 1

x = 35

Explanation:

Knowing that:

• m is parallel to n
• m (2x-13) degree
• n 123 degree

Background knowledge:

Straight line = 180 degree

Solve:

2x-13 + 123 = 180

2x +110 =180

2x + 110 - 110 = 180 - 110

2x = 70

x = 35
