An engineer on the ground is looking at the top of a building. The angle of elevation to the top of the building is 22°. The engineer knows the building is 450 ft tall. What is the distance from the engineer to the base of the building to the nearest whole foot?

Thank you!cool

tan(22°) = 450 / d       where d is the distance to the building......rearrange

 

d  = 450 / tan(22°)  =  about 1114 ft

 

 

 

cool cool cool
