Answer:
Step-by-step explanation:
Coordinates of Point b
b lies on the circle whose equation is
Comparing with the general form a circle with center at the origin:
The radius of the circle =17 which is the length of the hypotenuse of the terminal ray through point b.
For an angle drawn in standard position through point b,
x=-8 which is negative
y=15 which is positive
Therefore, the angle is in Quadrant II.
