Who just came to Canada to help me solve the following problems? I'm not good at math, and I don't have a calculator as a guide. I need it urgently! ! ! !
1. inclined height, h = 2.6m/sin15 =10.05m.
2 . a)angleA = cos- 1(3/8)= 67.9 = 68
angleC=sin- 1(3/8)=22
B) The radical sign under BC = (64-9) = 7.4.
