We often learn about the Trig functions in terms of opposite, adjacent and hypotenuse. We don't always learn about them in terms of coordinates. Here's a translation guide:
opposite = y
adjacent = x
hypotenuse = (Note: this is always positive!)
So
To find the answers to your question, just take your x, -3, and your y, -5, and plug them into the appropriate formulas above. Since cos has a square root in the denominator you will need to rationalize the denominator.
