Answer:
The correct answer is C. 15/12
Step-by-step explanation:
To find the value, we need to note that the csc is equal to the hypotenuse divided by the opposite side.
We know the hypotenuse to be 15 since it completes the Pythagorean triple. So we can plug these values in to solve.
CSC = Hyp/Opp
CSC = 15/12
