Find the least positive angle measurement that is coterminal with - 100°.

260°

Step-by-step explanation:

Co terminal angles are angle ± 360°n where n = 0, 1, 2, 3, ...

The least positive = - 100° + 360° = 260°

260 degrees is coterminal with - 100 degrees.

Step-by-step explanation:

So a full rotation about a circle is 360 degrees.

So if we do 360 + (-100) we get 260.

They will share the same terminal ray because if we go 100 clockwise from the initial ray that will be an angle coming counterclockwise 260 from the initial ray.

100+260=360.
