Answer:

52

Step-by-step explanation:

The square means that the angle is a right angle, measuring 90 degrees.

90 = 50 + (x - 12)

Subtract 50 from both sides.

40 = x - 12

Add 12 to both sides.

52 = x

X=52
it’s a right angle so the entire thing is 90. you already know the 50 so put it aside for now. take the whole 90 and add 12 bc you gotta do the opposite of what it says (-12) and then you get 102. then subtract the 50 and you get 52.
