... Start with a free body diagram. On the problem below, in the x direction you have simply the x components of the tension in each string. -T1x + T2x = 0 or T2x = T1x since the x component of T1 is in the negative direction, this will work out. T1x = T1cos(70) and T2x = T2 cos(50) In the y direction t ...
