Trigonometry Functions of Any Angle CAA point on the terminal side of angle O is given. Find the exact value of the indicated trigonometric function of e.1) (12, 16) Find csc 0.I need help with #2

1) I'll calculate the hypotenuse
hyp = squared root [(16)^2 + (12)^2]
= squared root [ 256 + 144]
2) the answer is letter C. 5/7
3) calculate the hypotenuse
hyp = squared root [(2^2 + (-3)^2]
= squared root [ 4 + 9]
= squared root [13]
sin 0 = -3/squared root 13
= -3squared root (13) / 13
The answer for number three = letter B
