Meteorologists find the height of a cloud using an instrument called a ceilometer. It 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 July 2, 2021, at Midway Airport in Mumbai, a ceilometer was employed to find the height of the cloud cover. It was set up with its light detector 50 meter from its light projector. If the angle of elevation from the light detector to the base of the cloud was 60°, what was the height of the cloud cover?

Step-by-step explanation:
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 delector is 65°, what is the height of the cloud cover? Guidol dlouds La Orolo 2. From the top of a building that overlooks an ocean, an observer watches a boat sailing directly toward the building. If the observer is 100 feet above sea level and if the angle of depression of the boat changes from 20° to 35º during the period of observation, approximate the distance that the boat travels.
