Dunno about that. I equated like finding the value of T through sin and cos values, to find a tan value.
And used that tan value to calculate tension.

thats easy, you just simply multiply the tension by the distance moved.
because the girl is the source of tension.

ya , but u had to multiply force with cos theta
because the force is not in same direction of motion
