please help me with this, keep messing up.
show your work please. I think i did it in the wrong quadrant.
5 and 12 are 2 sides of a Pythagorean triple triangle. The hypotenuse is 13. Therefore the cosine has to be 12/13. Since this in the third quadrant (the tan is positive and the sin is negative), the cosine is negative also.
