To find the distance across a river, a surveyor chooses points A and B, which are x = 50 ft apart on one side of the river (see the figure). She then chooses a reference point C on the opposite side of the river and finds that zBAC = 82° and LABC = 52°. Approximate the distance from A to C. (Round your answer to the nearest foot.) ft A x ft B 82° 52

Use the map in Figure 11.2. a. Find the grid section of the Parking Garage. b. What is located in section 2C?

For the triangle shown, A=30, B=45, and a=32 centimeters. Find the remaining angle and sides.

Use the angle values given to find 2. a. If 1 = 37, find 2. b. If 1 = 29, find 1.

Albert lives in New Orleans. At noon on a summer day, the angle of elevation of the sun is 84. The window in Alberts room is 4.0 feet high and 6.5 feet wide. (Sec Figure 24.) a. Calculate the area of the floor surface in Alberts room that is illuminated by the sun when the angle of elevation of the sun is 84. b. One winter day the angle of elevation of the sun outside Alberts window is 37. Will the illuminated area of the floor in Alberts room be greater on the summer day, or on the winter day? Figure 24
