Chapter 6.1, Problem 70PE

Software used to program video games often uses an origin at the top left of the display canvas. The positive $x\text{-axis}$ is to the right and the positive $y\text{-axis}$ is downward. Suppose that a player moves on a direct path from the origin to a point $P$ with pixel location $\left(135,200\right)$ . Then the player moves directly to point $Q$ at a pixel location of $\left(420,150\right)$ .

a. Find the player's bearing from the origin to point $P$ . Round to one-hundredth of a degree.

b. Find the player's bearing from point $P$ to point $Q$ . Round to one-hundredth of a degree.
