Answer:
90 Degrees
Step-by-step explanation:
This is a very cool theorem. When the longest side of a triangle is the diameter of the circle, which in the picture you can see it is, the angle opposite to it is ALWAYS 90 degrees. Remember that the points have to be on the circle for this theoroem to work. I forget what the theoroems is called, but it is very helpful.
Thanks and have a great day!
