Easy.

When you combine all the angles of the triangle, the sum will be 180°.

Angle 1 is 30% of 180 which is 52. This means angle 1 is 54°.

Angle 2 is 25% of 180 which is 45. This means angle 2 is 45°.

The sum of all the angles is 180° so angle x + 54° + 45° = 180°.

To find x, subtract 54 from 180 to get 126. Then subtract 45 from 126 to get 81.

This means angle x is 81°.

The value of x is 81.
