How to find t1,t2 when only given t3

[link107]

Homework Statement

Determine the magnitude of vectors T1
& T2 such that the sum of all the
vectors is zero.
Use T3 = 127.4

Homework Equations

The Attempt at a Solution

I tried to plot it out and stuff but I never worked with these kinds of problems what is a good way to solve for t1 and t2 when only given the angles. t1 angle = 37 degrees north west, and t2 angle is 53 degrees north east? while t3 has no angle given just it's magnitude which is 127.4 how would I solve? for t1 and t2's magnitude using the information listed?

From the given data can you find the angle between T₁ and T₂?
Do you know how to find the components of vector along the resultant?
