A player in a video game must knock out a target located 84 pixels above and 156 pixels to the left of his position. Choose a polar coordinate system with the player at the pole and the polar axis extending to the player’s right. Find the polar coordinates of the target (this determines the distance and angle at which the player should fire his gun). Find r to the nearest pixel and θ in degree measure to the nearest tenth of a degree.

System that uses coordinates to uniquely determine the position of points. The most common coordinate system is the Cartesian system, where points are given by distance along a horizontal x-axis and vertical y-axis from the origin. A polar coordinate system locates a point by its direction relative to a reference direction and its distance from a given point. In three dimensions, it leads to cylindrical and spherical coordinates.
Identify which quadrants in the polar coordinate system the following points lie.
1. (5,9π/7)
2. (-5, 6π/7)
3. (-5,3π/7)
4. (5,-4π/7)
Convert the point (-12,-5) into a polar coordinate. Represent the coordinate in 3 different ways -360°≤θ≤360° (Round to 1 decimal place)
Guadalupe boards a Ferris wheel at the 3-o'clock position and rides the Ferris wheel for multiple rotations. The Ferris wheel's radius is 15 meters
long and the center of the Ferris wheel is 19 meters above the ground. Imagine an angle with its vertex at the Ferris wheel's center that subtends the
path Jane has traveled.
The Ferris wheel rotates at a constant rate so that the angle sweeps out 7 radians per minute. How long does it take for Guadalupe to complete one
full rotation around the Ferris wheel?
