Angle M has a measure between 0 and 360 and is coterminal with a –620° angle. What is the measure of angle M?
100°
110°
120°
130°

Respuesta :

Two angles are said to be coterminal if when they are drawn in a standard position, their terminal sides are on the same location. A coterminal angle can be determined by adding or subtracting 360 degrees to the given angle. Thus, for the given -620 degrees angle we add continuously 360 until we find an angle that is in the choices.

-620 + 360 = -260-260 + 360 = 100

Therefore, Angle M is equal to 100 degrees. 

The measure of the coterminal angle is 100°.

What is the measure of angle M?

We know that for an angle A, all the coterminal angles B are of the form:

B = A + n*360°

Where n is an integer number.

Then we must find M such that:

M = -620° + n*360°

and:

0 < M < 360°

Notice that if we take n = 2 we get:

M = -620° + 2*360° = 100°

The measure of angle M is 100°
