Determine the angle (from due north) that the captain of the first boat needs to position their telescope to watch the second boat. Express your answer in terms of
, the amount of time since the second boat was due north of the first.
Draw and label a diagram. Use consistent units.
Write an equation with
and . Use sine, cosine, or tangent.
If the boat that is traveling north wants to catch the boat that is traveling east, what direction will the boat need to head to catch up to the eastbound boat? How long will this take?
Draw a new diagram. The boat traveling due north will now travel at an angle.
Write equations with
and/or . Use sine, cosine, tangent, and/or the Pythagorean Theorem.
