Answer:
x=25°
Step-by-step explanation:
The given angle is a 90° angle. We know this because of the little square in the corner. This means that both angles must add up to 90°:
[tex]x+y=90[/tex]
Insert the known values:
[tex]x+65=90[/tex]
Solve for x. Subtract 65 from both sides:
[tex]x+65-65=90-65\\\\x=25[/tex]
The missing angle, x°, is 25°.
