An engineer on the ground is looking at the top of a building. The angle of elevation to the top of a building is 38°. The engineer knows the building is 300 ft tall. What is the distance from the engineer to the base of the building to the nearest whole foot?

Assuming we ignore how tall the engineer is:

Use the COTANGENT fxn

 

 

300COT(38) =384 ft
