Best ResponseYou've already chosen the best response.1for the laws of sine you need one angle and side. 180  7015=95 degrees is angle a a/sin(A) = b/sin(B) small letters denote sides, Capital letters denote Angles

Best ResponseYou've already chosen the best response.1Well in precal, we go back and forth from degrees to radians, In calculus, we stay in radian.

Best ResponseYou've already chosen the best response.0Wow in geometry we just stay in degree because we only use the calc of Sine, Cosine, and Tangent.

Best ResponseYou've already chosen the best response.1Yes, I forgot in geometry they also, stay in the land of degrees. If you plan to study the higher mathematics, you will have to visit the land of radian.
