A 4.50 kg block of gruyere cheese is suspended as shown. Rope 1 on the left has a tension of 28.3 N; rope 2 on the right has a tension of 40.5 N.

(a) What is θ1, the angle made by rope 1? (b) What is θ2? State each angle as the positive angle "inside" the triangle the ropes form.

3. 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!
