Homework Equations
The Attempt at a Solution
I understand you have to use some triangles and some trigonometry. But I am not sure how.
here is my attempt
120 X 9.81 = 1177.2 = c?
so a + b = C?
and a = half of c and b = half of c?
and then a = sin60 = half of c divided by a ?
I have no idea. please help
