A high fountain of water is located at the center of a square pool. Not wishing to get his feet wet, the student walks around the pool and measures its perimeter to be 20 m. Next, the student stands at the corner of the pool and uses a protractor to gauge the angle of elevation of the top of the fountain to be 55 degrees. In inches, how high is the fountain?
When a man stands near the edge of an empty drainage ditch of depth 2.80 m, he can barely see the boundary between the opposite wall and bottom of the ditch as in Figure (a) shown below. The distance from his eyes to the ground is h = 1.88 m. (Assume ? = 33.0°.)
Figure a. A man of height h stands a horizontal distance d left of an empty rectangular drainage ditch of depth 2.80 m. A ray starts at the bottom right corner of the ditch, extends up and to the left to the upper left corner of the ditch, and then reaches the man's eyes. The ray forms an angle ? with the vertical.
Figure b. A man of height h stands a horizontal distance xleft of a rectangular drainage ditch that is filled with water. A ray starts at the bottom right corner of the ditch and extends up and to the left to the upper left corner of the ditch at an angle ? with the vertical. Upon exiting the water, the ray bends to become less steep than the ray in water, and extends up and to the left to the man's eyes.
(a) What is…
A fountain of water is located at the center of a circular pool. Not wishing to get his feet wet, a student walks around the pool and measures its circumference to be 16.5 m. Next, the student stands at the edge of the pool and uses a protractor to gauge the angle of elevation at the bottom of the fountain to be 55.0°. How high is the fountain?
