Answer:

csc (- Ф) = -29/20

Explanation:

We know that:

csc Ф = 1/ sinФ ................. equation 1

csc (- Ф) = - csc Ф .............equation 2

Given that:

sin Ф = 20/29

Using equation 1:

csc Ф = 1/ (20/29)

csc Ф = 29/20

using equation 2:

csc (-Ф) = - csc Ф = -29/20

I hope it will help you!
