a.) To determine which of these mountain peaks would be visible from Oahu, consider that you are lying on a surfboard and looking “ straight out ” so that your line of sight is tangent to the surface of Earth at the point where you are. Make a sketch of the right triangle formed by your sight line, the radius from the center of Earth to the point where you are lying, and the line from the center of Earth through Lanai. b.) Assuming that the radius of Earth is 3960 miles, determine the angle formed at the center of Earth. c.) Determine the length of the hypotenuse of the triangle. Is Lanaihale visible from Oahu
Suppose that you are surfing off the southeastern shore of Oahu and a local surfer catches your eye. As a tourist, impressing them with your surfing abilities is out of the question, but maybe you can dazzle them with trig? You notice three mountain peaks on the horizon. You want to determine which mountains are visible from Oahu. The possible mountain peaks that can be seen from Oahu and the height (above sea level) of their peaks are given in the table.
