Use the Law of Sines to solve each triangle. 1) ∠𝐴 = 45o,∠𝐵 = 60o,𝑎 = 14
5)
A ship passes by buoy B, which is known to be 3000 yards from peninsula P. The ship is steaming east ⃡
2) ∠𝐴 = 30o,∠𝐴 = 135o,𝑏 = 4
3) ∠𝐴=76o,𝑎=14,𝑏=4
4) ∠𝐶=88o,𝑏=7,𝑐=7
along 𝐵𝐸 and ∠𝑃𝐵𝐸 is measured as 28o. After 10 minutes, the ship is at S and ∠𝑃𝑆𝐸 is measured as 63o. a) How far from the peninsula is the ship when it is at S?
b) How fast (in yd/min) is the ship traveling?
c) Ship speeds are often given in knots, where 1 knot = 6080 feet per hour. How fast is the ship traveling in knots?
