An angle that is coterminal with 30 degrees can be found by adding or subtracting multiples of 360 degrees. In this case, an angle coterminal with 30 degrees could be 390 degrees (30 + 360) or -330 degrees (30 - 360). Coterminal angles have the same initial and terminal sides, but may differ in number of rotations around the unit circle.

An angle coterminal with 30 degrees can be represented by 30 + 360n, where "n" is any integer. Examples of coterminal angles: 390, 750, 1110, 1470.
Any angle can be coterminal.
25 degrees.
The complement of any angle is the angle which adds to it to make 90 degrees. In this instance, an angle of 60 degrees adds to 30 to make 90 degrees. Therefore, the complement of 30 degrees is 60 degrees.
