2nd question is: if cot A=1.96000 and the acute angle A has to be determined, which one of the following expressions will give the seconds of the angle? Coices are: A. -0.01159 over -0.00806 x 60", B. 0.00806 over 0.01159 x 60", C. -0.00120 over -0.00141 x 60", D. neg 0.00141 over 0.00120 x 60"
Any help with either or both would be greatly appreciated, thanks
