Airport meteorologists keep an eye on the weather to ensure the safety of the flights. One thing they watch is the cloud ceiling, the lowest altitude at
which solid cloud is visible. If the cloud ceiling is too low the planes are not
allowed to take off or land. A searchlight located 200 meters from a weather
office is turned on. If the angle of elevation to the spot of light on the clouds
is 35˚, how high is the cloud ceiling? (Round to the nearest meter.)
