Now for lammi's theorem refer to this

Statement: If three co-planers forces P, Q, R be in equilibrium and the angles between them be p (between Q n R), q (between P n R) and r (between P and Q) then

P/sinp = Q/sinq = R/sinr

For the proof see the diagram

I've also included the image explaining the angles between the strings.

Plz do vote my efforts
