Two angles are vertical angles. One angle is labeled 2x. The other angle is labeled (x + 30). Find the value of x

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°
