Answer:
C. 69 (nice)
Step-by-step explanation:
Sine: Opposite side over hypotenuse
Cosine: Adjacent side over hypotenuse
Tangent: Opposite side over adjacent side
Respective to angle O, we are given the adjacent side, 5, and the hypotenuse 14, so we can use cosine.
cos(O)=5/14
O=arcsin(5/14)≈69.0752
The answer is 69.
