Airport meteorologists keep an eye on the weather to ensure the safety of airplanes. One thing they watch is the cloud ceiling. The cloud ceiling is 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.

One process a meteorologists can use to find the cloud ceiling at night is to shine a searchlight that is located a fixed distance from her office vertically into the clouds. Then, she measures the angle from the office to the spot of light on the cloud.

The search light is located 40 m from the office.

If the angle to the spot of light on the cloud is 38 degrees, how high (in m)is the cloud ceiling?(Round the answer in nearest tenths place)
