These are vertical angles, and so they would equal each other.
Set the two angles = to each other
2x + 2 = 3x - 52
move all x to one side, and all numbers without variables to the other
2x (-2x) + 2 (+52) = 3x (-2x) - 52 (+52)
2 + 52 = 3x - 2x
x = 2 + 52
x = 54
54° is your value for x
hope this helps
