It says that tan x + 5 is a factor, so when you factor this equation, you get (tan x + 5)(4sin x -3). From here you can take the inverse tan of -5, and the inverse sin of 3/4. This should give you the right answers.

If you have a hard time visualizing the factorization, you can chunk and then look for a zero, which happens to be -5 (they give it to you in the problem) and then long divide. Sam is right, it's much easier to factor than to put it in terms of sin and cos (or just sin. If you are really hardcore, you can take this approach, where you turn everything into sin. Keep in mind that this becomes ridiculous though.
