Monkey force diagram and tension problem

[TyChi]

1. Homework Statement

A 5kg monkey hangs initially at rest from two vines, A and B, as shown in the JPEG attached. Each of the vines is 10m long and has negligible mass.

a) Draw a force diagram labeling all forces acting on the monkey. (do not resolve the forces into components, indicate their directions though.)

b) What's the tention in vine B while the monkey is at rest?
