I apologize, I need a little bit of help...

I am thinking that it is D.

Determine which trigonometric function to use to solve for the hypotenuse. Then, solve for the length of the hypotneuse.

b = 9
A = 55.8
a.
cosine, .062
c.
sine, 16.0
b.
sine, 10.8
d.
cosine, 16.0

Yes D is correct.

anonymous · Answer

$$c=9 \sec (55.8 {}^{\circ})=16.0119 $$

anonymous · Answer

@robtobey  Are you saying that it is C? (I am sorry, I'm a little confused.)

anonymous · Answer

c/b =    sec(A)
c     = b sec(A)
