Have you been learning how to use trig functions?  Sine, cosine, and tangent?

miguel980 · Answer

Yes

anonymous · Answer

Ok, so in this problem you have the opposite side length and you're looking for the hypotenuse.  Do you know which trig function you would use here?

miguel980 · Answer

No because there is only one side length given

anonymous · Answer

Right, but we also know the angle.  

$$\tan \theta= opposite/adjacent$$ 
$$\sin \theta= opposite/hypotenuse$$
$$\cos 30= adjacent/hypotenuse$$

does that help?  There are three unknowns in each of the equations, but we already know two of them
