Have you learned  SOH CAH TOA ?

anonymous · Answer

Yes, does that mean its wrong lol :( my other guess was B

phi · Answer

to do this problem,  put your finger on the angle you know  (the 60 degree angle)
now label each of the 3 sides:  which side is *opposite* the angle, which side is *adjancent*,  and which side is the hypotenuse ?
can you label the sides?

phi · Answer

The hypotenuse should be easy to find:  it is the longest side, and it is the side opposite the 90 degree angle.
