So, by way of text messaging a former student asked for some reminders about "forces and angles" in what I'm assuming is a unit or course in mechanics.
I'm not entirely sure of what exactly you're looking for but I'll take my best guess and you can reply below by leaving a comment about what you still need to know.
Forces are vectors. When you're determining the Net Force on an object you will need to use some trigonometry. Usually I find a good diagram helpful here since you can form a triangle out of the sum of two forces (provided they're not in the same or opposing directions)with the third side being their resultant.
From here you will need either the Sine Law, or the Law of Cosines. You can also use x and y components of the forces if you have more than two.
