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.

Answer:
1.74%
Step-by-step explanation:
2.87-2.82=0.05
0.05/2.87=x/100
0.05x=287
