Help aaahhhh<br>x =x=x, equals <br><br>^\circ <br><br>∘<br><br> degrees
Ganezh [65]

Using supplementary angles, it is found that the measure of angle x is of 65º.

<h3>What are supplementary angles?</h3>

Angles are called supplementary if the sum of their measures is of 180º.

In this problem, angles x, 25, and 90º are supplementary, hence:

x + 25 + 90 = 180

x = 180 - (25 + 90)

x = 65º.

The measure of angle x is of 65º.
