point P on the unit circle is given (15/17,8/17). what is the sine of the angle formed by a terminal ray that intersects the unit circle at this point?
-8/17
-15/17
8/17
15/17
1 answer
The sine of an angle is equal to the y-coordinate of the point where the terminal ray intersects the unit circle. In this case, the y-coordinate is 8/17. Therefore, the sine of the angle is 8/17.
