.

Angles do not have coordinates.

Only points may have coordinates on a coordinate plane (or in a coordinate space).

Unit Circle is very typical and standard knowledge. See your textbook, and draw a Unit Circle yourself. The answers to each of the requested angles will be apparent.

Understand clearly, that 315° is the same as -45° ; so just look for this using your unit circle.
