Step-by-step explanation:
Hope the gif loads to help you but if not thats the answer.
The answer is 71°.
x = angle
3x = 90 - x - 14
4x - 76
x = 19°
90 - x = 71°
I think the answer is A. But I’m not fully sure
Simply collect all the like terms together

Maybe it’s 3 but it actually depends on the equation . . .
