Tell whether the angles are adjacent or vertical. Then find the value of X.

Answer: The angles are vertical, and X = 37°
Step-by-step explanation: Vertical angles are angles opposite to each other, and are congruent. Therefore, (3x-4) is going to be equal to 107°. So, we form the equation 3x - 4 = 107. After solving this equation, you get the answer x = 37°.
