basically I am trying to compare steps in this, which i copied off a handout , brushing up on my math skills I would like to see all the steps, which i cant seem to replicate, mainly from the first equation to the 2nd one, where did that other t2 go? haha i am using X instead of the t2 and i dont use the N but having not a heck of a lot of luck right now getting the step by step to show on wolfram
(T2cos60/cos30) sin30 + T2sin60 = 98N
The rest is just algebra...
T2 (cos60 sin30/cos30 + sin60) = 98N
T2 = 98N/(cos60 sin30/cos30 + sin60)
T2 = 98N / 1.155 = 84.9N
