How do you find csc 163degrees 20minutes? (I didn't know how to insert the degree and minute marks)

Answered by drwls
163 degrees 20 minutes is the same as the csc of its supplementary angle, which is 16 degrees 40 minutes. The sine of that angle is 0.2868
(I used a pocket calculator for that)
The cosecant is the reciprocal of the sine, which is
1/0.2868 = 3.4867
