By using a change from polar to rectangular coordinates, we will see that Oscar's location is (-6.93mi, -4 mi).
How to get Oscar's exact location?
In polar coordinates, we can see that Oscar 'slocation is defined by a radius of 8 miles and by an angle of 210° (we use 210° because we measure the angle from the positive x-axis).
Now, if we know the radius and the angle, the rectangular coordinates are just:
x = R*cos(angle)
y = R*sin(angle).
In this case, we will have:
x = 8mi*cos(210°) = -6.93mi
y = 8mi*sin(210°) = -4 mi
So, Oscar's exact position is (-6.93mi, -4 mi).
