Using what you told me from the last problem I think that the answer is 7 cos 33°

Not exactly if you remember SOH CAH TOA then you know that cos would be $$Cos \angle = Adjacent/Hypotenuse$$

anonymous · Answer

If we use the angle 33 we want to solve the side opposite of that and we only have the hypotenuse

anonymous · Answer

So the adjacent side would not work in this example

anonymous · Answer

Ohh. Then it would be 7 sin 33° because sine is opposite/hypotenuse right?

Correct! Great Job

Yes. Thank you!
