Answer:
x = 65
Step-by-step explanation:
The measure of the entire angle is 180°. The angle on the furthest left (with a square in it) is a right angle, meaning that it is 90°.
All three of the angles (90°, x°, 25°) all add up to the measure of the line, which is 180°. So, we can write this equation.
90 + x + 25 = 180
Subtract 90 and 25 from both sides.
90 + x + 25 - 90 - 25 = 180 - 90 - 25
x = 65
