Question

For the rotation –1068°, find the coterminal angle from 0° < < 360°, thequadrant and the reference angle.

Answer 1

The rotation is;

`-1068^o`

The coterminal angle can be gotten from adding 360 degrees repeatedly,

`-1068+360+360+360=12^o`

The quadrant is the first quadrant. Since 12 is less than 90

The reference angle is the acute angle between the line and the positive x-axis, this is;

`12^o`
