.Sam.Best ResponseYou've already chosen the best response.2
For both components, the sum of all forces is zero, since its not moving, For X component, \[T_2\cos(60)T_1\cos(20)=0\] \[T_2=\frac{T_1\cos(20)}{\cos(60)}\] For Y component, \[T_1\sin(20)+T_2\sin(60)25(9.81)=0\] \[T_1\sin(20)+(\frac{T_1\cos(20)}{\cos(60)})\sin(60)25(9.81)=0\] Solve for Tension 1, just ask if anything you're not sure.
