Answer:
x = 26
Explanation:
Since s║t and r is a transversal, consecutive interior angles add to 180
⇒ 2(x + 15) + (3x + 20) = 180
⇒ 2x + 30 + 3x + 20 = 180
⇒ 5x + 50 = 180
⇒ 5x = 180 - 50
⇒ 5x = 130
⇒ x = 130/5
⇒ x = 26
x=26
Given:
s || t
2(x+15) + (3x+20) = 180°
Since the sum of co interior angle is 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.
Therefore value of x is 26.
