Problem A14: In the figure below, a weightless plank has a weight W resting on it. It is held up by two strings having tensions of T1 and T2. The left string makes an angle &theta degrees with the horizontal, and the right string makes an angle of (90-&theta) degrees with the horizontal. The weight W has a value of W = n1 T2. The plank is n2 units long. What is the distance n3 that the weight W is from the left end of the plank? n3 = ? Note that n1 is unitless, and that n2 and n3 have the same units of length.

n1 = n2 = Input n3:
