T*cos(30)= Uk*(w-Tsin30) =



Is equal to:

T = Uk*W/(cos(30) + Uk*Sin(30))



I dont get it :<

expand the right hand side:
T*cos(30) = Uk*w - T*Uk*sin(30)

then move the term with T in it from the right side to the left side
T*cos(30) + T*Uk*sin(30) = Uk*w

factor T from terms on left hand side
T*[cos(30) + Uk*sin(30)] = Uk*w

isolate T by dividing by the remainder from that factoring process
T= Uk*w/[cos(30) + Uk*sin(30)]
