1. Meteorologists find the height of a cloud using an instrument called a ceilometer. A ceilometer consists of a light projector that directs a vertical light beam up to the cloud base and a light detector that scans the cloud to detect the light beam. On December 1, 2001, at Midway Airport in Chicago, a ceilometer with a base of 300 feet was employed to find the height of the cloud cover. If the angle of elevation of the light detector is 650, what is the height of the cloud cover? 2. from the top of a building that over looks an ocean, if the observer is 100 feet above sea level and if the angle of depression of the boat changes from 20°to 35° during the period of observation, approximate the distance that the boat travels ​
