Vertical angles are equal, so to find x, you must set the angle measures equal to each other 

Answer:

x = 30°

Step-by-step explanation:

Vertical angles are equal. Vertical angles are congruent angles. Vertical angles share the same vertices . They share the same corner points.

Since the two angles are vertical angle that means they are equal.

The first angle = 2x

the second angle = x + 30

To find the value of x

2x = x + 30

collect like terms

2x - x = 30

x = 30°
