I got A, -32, but it has been awhile since I have learned this in my math class. You might want to wait for someone else to verify this answer.
Answer:
The answer is "angle".
Step-by-step explanation:
There will be two legs as well as a hypotenuse inside the right triangle. Its legs are both at an angle of 90° as well as the length of a right triangle upon on hypotenuse half is the opposite side of a right angle. When you have the two-angle measurement as well as the right triangle height on one side, you can find equal measurements of two angles on another and the lengths for two sides on another.
