Since these two have the same power and variable, you can just subtract right away. It’s going to be 7x^1/5
- 10x - 11 = -12x + 21

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°
