You know the weight is 3.7 x 9.8 = 36.26N vertical component steel ball.

First find t1 = 36.26/cos(35) = 44.265N

The steel ball is in equilibrium, so the sum of the forces on it is zero.

draw a vector diagram and use it to find t2, this will be the sq-rt of (t1^2 - vertical component (36.26^2)).Alternatively use t1 x sin(35)

t2=
