Question

I need help with answer 9 have a test tomorrow

Answer 1

csc is the reciprocal of sin, so the answer is 7/3

Answer 2

csc θ = 7/3  
OK. Problem 9 gives you the sine and cosine of θ and wants you to determine the cosecant of θ. In order to do this, you need to remember the definition of cosecant which is simply the reciprocal of the sine. Since the sine of θ is 3/7, that means that the cosecant of θ is 7/3.
