180-165 = 15
90+15 = 105
180-105 = 75
Since opposite angles are equal, x = 75.

Its shown in the figure that the triangle is 90°. So by subtracting 180 and 165, we get one of the angles, which is 15. We also know that sun of interior angles of a triangle is 180°. Thus, we added two angles, 90+15 and got the third angle 75.
