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