Find the value of X in the image below.

Answer 1

32°

Explanation:

l₁ // l₂ and t is transversal. co interior angles are supplementary.

3x + 20 + 2x = 180

3x + 2x + 20 = 180

5x + 20 = 180

Subtract 20 from both sides,

5x = 180 - 20

5x = 160

Divide both sides by 5,

x = 160 ÷ 5

x = 32

Answer 2

x = 32

Explanation:

(3x + 20) and 2x are same- side interior angles and sum to 180° , that is

3x + 20 + 2x = 180

5x + 20 = 180 ( subtract 20 from both sides )

5x = 160 ( divide both sides by 5 )

x = 32
