Using your calculator find the csc200degree Solve the follow

Using your calculator, find the csc(-200^degree). Solve the following right triangle. a = 10 alpha = 50^degree

Solution

9. csc(-200)degree

csc theta=1/sin theta

therefore csc(-200)=1/sin(-200)= 2.9238

10. tan alpha=opposite/adjacent=a/b

And alpha=50 degree    and a=10

tan 50=10/b

b=10/tan 50= 8.39

sin alpha=a/c

sin 50=10/c

c=10/sin50=13.054
