For each of the following angles, find a coterminal angle with measure (theta symbol) such that 0 degrees is greater than or equal to omega symbol < 360 degrees.
a) 100 degrees.
I really do not understand how to work this problem and I need help.

Generally angles are expressed as values between 0 and 360 degrees.
Since there are 360 degrees in a circle, adding or subtracting 360 from the value will not change the terminal point of the angle. It just means you have done an extra clockwise or counterclockwise rotation about the origin.
So, 100° represents the same angle as all of the following:
... 820° 460° 100° 260° 620° ...
so, which of those values is between 0° and 360°?
