Problem 1.2 1.2 In the right triangle ABC shown, c = 25 ft and angle A = 48. (a) Determine side a. (b) Determine side b. (c) Determine height h. Problem 1.10 b C a B One side of a triangular lot is 100 ft and the angle opposite this side is 55. Another angle is 63. Sketch the shape of the lot and determine how much fencing is needed to enclose it. Problem 1.37 Two people fishing from rowboats on a lake are 100 m apart and have hooked their lines into the same sunken log. The first has 85 m of line out, and the second has 68 m of line out. Assuming that the lines both lie in the same vertical plane, meet at a point (on the log), and are taut, how deep is the sunken log? 100 m 85 m u 9 Log I
