Answer: x = 25°, y = 60°

Explanation:

It is given that the box represents 90 degrees. Now, we can use the angle addition postulate to solve for x.

x + 65° = 90°

x = 25°

It is given that a straight angle is equal to 180 degrees, we can use this and the angle addition postulate to solve for y.

y + 30° + 90° = 180°

y + 120° = 180°

y = 60°
