T1cos alpha=T2cos beeta--eqn1T1sin alpha+T2sin beeta =mg--eqn2Firstly from eqn 1 obtain T2In eqn2 put the value of T2 and obtain T1And then again put the value of T1 in T2Then finally you will get answer

So T1 makes alpha and T2makes beta then vertical components balance will giveT1sin(alpha) + T2sin(beta) = mgHorizontal components T1cos(alpha) = T2cos(beta)T2= T1cos(alpha). / cos (beta)T1sin(alpha)+T2 tan( beta)*cos(alpha)=mgT1=mgsec(alpha)/(tan(alpha) + tan(beta)

It`s solve by Levi`s Theorem:-->T1/sin(90+β)=T2/sin(90+α)=TE/sin(180-sinβ+sinα).Then---->T1/cosβ=T2/cosα=T3/cos(β+α).
