Gravity Formulas urgent

I have to find the gravity acting upon an object, given an ANGLE. What would be the simplest formulae to use, I forgot my wrk sheet at school. I just need the simplest formulae, i found some but these are hard for me, we didn't use these (I'm in grade 11);

wait i found this would it work: a = (g) sinx

Perhaps you have not written the question very well, but answer the following:

You have a mass of 100kg. What is the force of gravity acting on you [magnitude and direction] when you are standing still, on the Earth where g = 9.8?

What is the force of gravity acting on you while you jump on a trampoline?

What is the force of gravity on acting you when you are in a lift?

What is the force of gravity on acting you when you are riding a roller coaster?
