Answer:
The measure of is 30°.
Step-by-step explanation:
In the statement, the angle has been misrepresented. The corrected statement is described below:
<em>"On a unit circle, the terminal point of </em><em> is </em><em>. What is </em><em>?"</em>
The measure of the angle (), in radians, is in standard form, that is, it is done with respect to the +x semiaxis. The measure of the angle whose terminal point is of the form is determined by the following inverse trigonometric function:
(1)
If we know that and , then the measure of is:
The measure of is 30°.
