Answer 1

x = 26

Explanation:

sum of consecutive interior angles is 180

2(x + 15) + (3x + 20) = 180

2x + 30 + 3x = 160

5x = 130

x = 26

Answer 2

value of x is 26.

Explanation:

Given:

2(x+15)°+(3x+20)°=180°

Since the sum of angle of co interior angle is supplementary.

Solving for x.

2(x+15)°+(3x+20)°=180°

• opening bracket

2x+30+3x+20=180

• Solving like terms

5x+50 =180

• Subtracting both side by 50.

5x=180-50

5x=130

• dividing both side by 5.

x=130/5

x=26

Therefore value of x is 26.
