Homework Statement
Hello, we were given homework, which is perfectly described by this picture. We should figure out F1 and F2 (it's number). I know that if the both angles are equal, it is easy to solve. However, now i should solve a situation when first angle (alpha) = 50 grades, the second (beta) = 25 grades - they are not the same
Furthemore, i know that weight of the man is 70 kg. We should find out F1 and F2.

Homework Equations
of course Fg = m.g so Fg = 700N (approximately)
The Attempt at a Solution
Now i know that if the 2 parts of rope are equals, it can be solve in this way : Fg/2 = F1 . sin alpha and both forces (F1 and F2) would be equal. However, i do not know what will happen if the angles are not equal
Thank you really much for your help!
