Homework Help: Physics

I was just a little confused with this problem and was hoping for some help or a nudge since the only value given is 27 degrees. Thanks for your time!

George of the Jungle, with mass m, swings on a light vine hanging from a stationary tree branch. A second vine of equal length hangs from the same point, and a gorilla of larger mass M swings in the opposite direction on it. Both vines are horizontal when the primates start from rest at the same moment. George and the gorilla meet at the lowest point of their swings. Each is afraid that one vine will break, so they grab each other and hang on. They swing upward together, reaching a point where the vines make an angle of 27.0° with the vertical.

(a) Find the value of the ratio m/M.
