Question

Find the value of the variable.

Answer 1

Var ‘x’ = 14.

The angle reflecting 110 degrees is also 110 degrees.
110 * 2 = 220 degrees.

Out of a 360-degree division, 360 - 220 = 140 degrees (5x degrees + it’s reflected angle.)

2(5x) = 140
10x = 140
x = 14

Answer 2

These angles are supplementary, meaning that their sum should be 180.

Write an equation.

5x+110=180

5x+110-110=180-110

5x=70

x=14

To find the angle measure,

multiply 5 by 14.

5 x 14= 70

To check:

70+110=180

Therefore, the variable has a value of 14.
