Two guys wire from the top of a 30 ft tent pole are anchored to the ground below by two stakes. The tent pole is perpendicular to the ground and between the two stakes. If the angle of depression from the top of the pole to each of the stakes are 42 degrees and 48 degrees, how far apart are the stakes? Round your final answer to one decimal place!

If the angle of elevation to the sun is 74.3 when a flagpole casts a shadow of 22.5 feet, what is the height of the flagpole? a. 63.2 feet b. 79.5 feet c. 83.1 feet d. 80.0 feet

A 2.10-ft side, a 3.05-ft side, a 2930' angle opposite the 3.05-ft side.

An amusement park ride the Octopus has eight support arms that are equally spaced about a circle. What is the measure of the central angle formed by two consecutive arms?

A single-threaded (or single-start) square-thread screw is shown in Figure 5-6. The lead of a screw is the distance that the screw advances in one turn (revolution). The lead is equal to the pitch in a single-threaded screw. Given the number of turns and the amount of screw advance, determine the leads.

Which angle is coterminal with 160 ? a. 50 b. –70 c. 20 d. –200

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
