2 questions, i know they have been answered before in other threads but i did not really understand those answers.
(1) Degrees are not the only units we use to measure angles. We also use radians. Just as there are 360 degrees in a circle, there are 2pi radians in a circle. Compute tan pi/3.
(2) In triangle GHI, we have GH = HI = 25 and GI = 30. What is sin GHI?
Thanks
