Answer:
x = 30
Explanation:
In the figure attached,
Two lines are parallel and one line having two adjacent angles (4x)° and (x + 30)° are the transverse.
Sum of interior consecutive angles = 180°
So the sum of these angles = 180°
(4x)° + (x + 30)° = 180°
(4x + x) + 30 = 180
5x + 30 = 180
5x = 180 - 30
5x = 150
x = 30
Therefore, value of x = 30
