Question

Given 1 || m ||
n, find the value of x.
m
140°

Answer 1

x = 16

Explanation:

(8x + 12)° = 140°

8x + 12 = 140

8x = 128

x = 128 ÷ 8

x = 16

Answer 2

x = 16

DISREGARD 16.5 MY BAD the answer is 16

Explanation:

140 = 8x+12

Subtract 12 on both sides

128 = 8x

Divide by 8

16 = x

x = 16
