This document discusses the solutions to tide problems. It provides cosine and sine values for variables A, B, C, and D. It then states that the time at which the water level will first reach 1.25 feet is 1:47 a.m.

1. Solutions 2 Tides

2. a.)

3. Cosine A = 2 B = C = 0 D = 0 Sine A = 2 B = C = 9.375 D = 0 Cosine 2 A = -2 B = C = 6.25 D = 0 Sine A = -2 B = C = 6.25 D = 0 b.)

4. c.) LET: The time at which the level of water will first reach 1.25 feet is at 1:47 a.m.
