HELP!!! What is the cosine of the angle in standard position in which the terminal side passes through the point (-5, 12).

OpenStudy (mathmale):

1) sketch this situation. Use the Draw utility, below. 2) What is the definition of the cosine of an angle named x? Define it in terms of its leg(s) and its hypotenuse. 3) Draw such an angle, measuring counterclockwise from the positve x-axis. 3. What is the value of the cosine of this angle?

I think that is one of the famous triangles with sides 5,12,13
