For each of the following angles, find a coterminal angle with measure (theta symbol) such that 0 degrees is greater than or equal to theta symbol < 360 degrees.

a) -100 degrees.

I really do not understand how to work this problem and I need help

a. A = -100 + 360 = 260o.

To find a coterminal angle with a given angle, you need to add or subtract a multiple of 360 degrees until you obtain an angle within the desired range (0 degrees to 360 degrees).

In this case, you have an angle of -100 degrees. Since -100 is negative, you need to add multiples of 360 degrees until you reach a positive angle. Start by adding 360 degrees to -100:

-100 + 360 = 260

The angle 260 degrees is still within the range 0 to 360 degrees, but it is not the only coterminal angle. You can continue adding or subtracting 360 degrees until you find other coterminal angles:

260 + 360 = 620 (outside the desired range)

260 - 360 = -100 (same as the original angle, but negative)

Therefore, the coterminal angle with -100 degrees in the desired range is 260 degrees.
