1. ## 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:

$0.25T \sin \theta + 4.88 T \cos \theta = 50510.8$

where $\theta$ = 21 degrees. This is the same as:

$T(0.25 \sin \theta + 4.88 \cos \theta) = 50510.8$

Rearrange to get:

$T= \frac {50510.8}{0.25 \sin \theta + 4.88 \cos \theta}$

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

Thanks very much
