Can u pls help I need a good grade

15

Step-by-step explanation:

Any triangle adds you to 180

Because it is a right triangle it will automatically  have 90°

Now you know 90° and 75°. You add it up and get 165°

Then you take the sum of all angles which is 180° and you do 180°-165°.

Your answer is 15°. it is an acute angle because it is below 90°

4th option is correct xy=-10

if this was to u plzz mark me the brainliest
