Find magnitude of the force of tension?

[TLink11]

Homework Statement

About 50 years ago, the San Diego Zoo, in California, had the largest gorilla on Earth: its mass was about 3.10 * 10^2 kg. Suppose a gorilla with this mass hangs from two vines, each which makes an angel of 30 degrees with the vertical. Draw a free-body diagram showing these various forces, and find the magnitude of the force of tension in each vine.
m = 310kg
angle of each vine = 30
g= 9.8 m/s

Homework Equations

Force = m * g

The Attempt at a Solution

F = 310 * 9.8 = 3038N
Cos30 * 3038N = 2630.985177N <- Would this be the tension for each vine? I'm not good at physics so I need confirmation/help.

No, it doesn't work out that way.
Did you draw a free-body diagram showing all the forces acting on the gorilla? Do that, then answer these questions:

What is the downward force (or forces) acting on the gorilla?
What is the upward force (or forces) acting on the gorilla?

That should help you towards solving the problem.
