The Attempt at a Solution
I tried to solve for one of the thetas using the equation for the x-axis
T1cosθ1+T2cosθ2 = 0
and then substitute it in the equation for the y-axis *trying* to use the trig identities
T1sinθ1+T2sinθ2 = mg
I doubt I'm doing it right but either way I'm way stuck after an hour
help!please!
