The other person is literally wrong. The answer is D. Supplementary because two angles that add up to 180 are supplementary angles.
The Pythagorean theorem is with right triangles. You know that a right triangle is formed from first to the mound to home-plate. So when you draw it out and label the sides you have one missing side. the Pythagorean theorem is a^2 + b^2 = C^2. the c side is always the slanted side. In this case the c side would be from homeplate to first base. So you just have to solve now. (33)^2 + (50)^2 = c^2. So 1089 + 2500 = c^2. Add together and you get: 3589 = c^2. Lastly take the square-root of 3589 and that is the answer. 59.9. So the answer is 59.9 feet.
missing side is 
mi .
<u>Step-by-step explanation:</u>
Here we have the following info from the figure: A right angled triangle with following dimensions
By Pythagoras Theorem :
⇒
⇒ 
⇒
