The measure of an angle in standard position is given. find two positive angles and two negative angles that are coterminal with the given angle. (enter your answers as a comma-separated list.) 5π 4

You can add and subtract suitable multiples of 2π to find your co-terminal angles.

5π/4 + 2π = 13π/4
5π/4 + 2·2π = 21π/4
5π/4 - 2π = -3π/4
5π/4 - 2·2π = -11π/4

Your angles can be {-11π/4, -3π/4, 13π/4, 21π/4}.

45x is the correct answer
