DIG DEEPER! Objects detected by radar are plotted in a coordinate plane where each unit represents 1 mile. The point (0,0) represents the location of a shipyard. A cargo ship is traveling at a constant speed and in a constant direction parallel to the
coastline. At 9 A.M., the radar shows the cargo ship at (0,15). At 10 A.M., the radar shows the cargo ship at (16,15). How far
is the cargo ship from the shipyard at 4 P.M.?

61.7 degrees

Step-by-step explanation:

The problem is asking for the degree of angle A, so I assumed that is what I am supposed to find.

When looking at the problem, you would find that you are given the hypotenuse and the side adjacent to angle A.

Therefore, you would use the cosine function, adjacent/hypotenuse, to find the answer of the angle. You would take the inverse since you are solving for the angle.

Hope this helped!
