Re-arranging Trig equation

Hi,

Doing a tension in cable problem, Trying to find T, ended up with this, can this be arranged to find that? If so, an explanation would be very helpful

0.25(T*sin21) + 4.88(T*cos21) = 50510.8

Thanks

You have:



where = 21 degrees. This is the same as:



Rearrange to get:

Seems so simple when written like that. i was expecting something more complicated.

Thanks very much
