**drwls**, Monday, March 19, 2012 at 6:29am50/130 is the sine of the angle the string makes with the wall. That angle is therefore A = 22.6 degrees. (The string, wall and horizontal form a 5-12-13 right triangle)

Now write horizontal and vertical force balance equations and solve for P and T. (T is the tension)

The vertical equilibrium equation will be:

T cos22.6 = M g

so you can already solve for T.

The horizontal equilbrium equation is

T sin22.5 = P

You finish it.
