Point P(k, 24) is 25 units from the origin. If P lies on the terminal arm of an angle in standard position, determine the measures of the angle(s)

Answer 1

Learn to recognize the easy Pythagorean triples. One of these is 7-24-25

Or, if you want to figure it out, just work with

k^2 + 24^2 = 25^2

Now you can find the angles.
