Answer:
x = 25°
y = 65°
Explanation:
One angle is marked with the small square showing it is a right angle. Two pieces are x and 65°. These will add together to make 90°.
Use this idea to write an equation:
x + 65° = 90°
subtract 65 from both sides.
x = 90 - 65
x = 25°
x + y also add up to 90°.
x + y = 90°
25° + y = 90
subtract 25°
y = 65°
