A rod with a length of .5m and mass of 10 kilograms is suspended from a ceiling by two strings which have lengths of .42m (L2) and .29m (L3). Solve using the laws of cosines.
I have found the angles, A , B, and C.
Once at equilibrium what is the elevation angle theta from the x-axis to the rod?
What are the tensions in the two strings?

2. Relevant equations
c2 = a2 + b2 – 2ab cos C
a2 = b2 + c2 – 2bc cos A
b2 = a2 + c2 – 2ac cos B.
Torque equations, force equations...
3. The attempt at a solution
Angles:
A = 35.48
B = 87.41
C = 56.99
