Question

Which expression finds the measure of an angle that is coterminal with a 300° angle?

300° – 860°
300° – 840°
300° – 740°
300° – 720°

Answer 1

The expression that gives an angle that is coterminal with 300 is 300-720. Two angles are said to be coterminal if when they are drawn in a standard position, their terminal sides are on the same location. The expression gives an angle of 420 where when it is drawn the terminal sides are on the same location with the 300.

Answer 2

The correct answer is:

300° – 720°

Step-by-step explanation:

Coterminal angles are angles that, when drawn in standard position, have terminal sides in the same place.

Any angles that are coterminal are some multiple of 360° different in measure. This is because in order to be coterminal, they must travel the entire circle at least once, possibly more times.

Out of the given options, the only one that is a multiple of 360° is 300° – 720° .
