You stand in a flat meadow and observe two cows $($see the figure below$).$ Cow A is due north of you and $15\mathrm{.}5$ m from your position. Cow B is $23\mathrm{.}0$ m from your position. From your point of view, the angle between cow A and cow B is $20\mathrm{.}5\backslash$deg $,$ with cow B appearing to the right of cow A$.$ You might want to use law of cosines rather than law of sines, since the law of sines is ambiguous with obtuse angles: sin$(\backslash$theta $)=$sin$(180-\backslash$theta $)$

$($a$)$ How far apart are cow A and cow B$?$

m

$($b$)$ Consider the view seen by cow A$.$ According to this cow, what is the angle between you and cow B$?$ The angles are measured in a standard mathematical grid, with zero degrees at the positive x$-$axis, and $180$ degrees at the negative x$-$axis.

$\backslash$deg

$($c$)$ Consider the view seen by cow B$.$ According to this cow, what is the angle between you and cow A$?$ Hint: What does the situation look like to a hummingbird hovering above the meadow?
