I need help on this question I don’t understand

Answer:

x = 25

Step-by-step explanation:

Since these 2 angles are vertical angles, then they are both equal. Set up an equation and then solve it.

75 = 4x - 25

75 + 25 = 4x

100 = 4x

100/4 = 4x/4

25 = x

Hope this helps. Brainly will be highly appreciated.
