# 8. Two swimmers, Andy and Becca, begin a race standing 50 feet apart on a shoreline. Becca will swim perpendicular to the shore, while Andy will swim at a 75° angle to the shore. They race toward a buoy in the lake, at point C. 50 ft a = 75° B = 90° sin 75° (a) Which trigonometric ratio: cos 75° can be used to determine the length BC? tan 75° Then, find an exact expression for the length BC, and an approximation rounded to two decimal places. sin 75° cos 75° tan 75⁰ Then, find an exact expression for the length AC, and an approximation rounded to two decimal places. (b) Which trigonometric ratio: Circle one. can be used to determine the length AC? Circle one. # 8. Two swimmers, Andy and Becca, begin a race standing 50 feet apart on a shoreline.
