Best ResponseYou've already chosen the best response.0Several ways to this, higher math use double integrals polar. However, it could be done geometrically. Calculate the area of the triangle; calculate area of semicircle; Subtract

Best ResponseYou've already chosen the best response.1lets get the larger angle; using law of cos; in a good way lol 6^2 = 4^2 + 4^2  2(4)(4) cos(C) 36  16  16  = cosC; C = cos^1 of that stuff right? 32
