D since (-5 x -5) = 25 and (7 x -8) = -56. Add 25 and -56 and your answer is D. -31

So we can only find x if other two angles of triangle is given.
In angle B as u can see boxed shape angle is there then it probably means it's a 90° angle.
We know sum of angles of triangle = 180°
{Reson :-
There's a formula to fund sum of angles of figure
- (n-2) × 180
- (3 -2) × 180
- 1 × 180
- 180°
}
Now Let's proceed

Fill all the given values








Value of x = 35°
