Question

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

Answer 1

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
