Answer:
x = 67.4°
y = 22.6°
Explanation:
The tangent ratio is a trigonometric ratio that relates the ratio of the length of the side opposite an angle in a right triangle to the length of the side adjacent to that angle.

Angle x
The side opposite angle x is 7.2, and the side adjacent angle x is 3.
Use the tangent trigonometric ratio to find the measure of angle x:

Therefore, x = 67.4°.
Angle y
The side opposite angle y is 3, and the side adjacent angle y is 7.2.
Use the tangent trigonometric ratio to find the measure of angle y:

Therefore, y = 22.6°.
