Solve the problem.
-Suppose you would like to cross a 207-foot wide river in a boat. Assume that the boat can travel 37 mph relative to the water and that the current is flowing west at the rate of 7 mph. What bearing should be chosen so
That the boat will land at a point exactly across from its starting point? Give your answer to the nearest tenth of
A degree.
A) 7.3°
B) 8.7°
C) 10.9°
D) 79.1°

To counteract the 7 mph westward current, the boat must have an eastward component of velocity equal to 7 mph. Using trigonometry, the angle θ can be found using sin(θ) = 7/37, which gives θ ≈ 10.9°.
