An engineer on the ground is looking at the top of a building. The angle of elevation to the top of the building is 46°. The engineer knows the building is 250 ft tall. What is the distance from the engineer to the base of the building to the nearest whole foot?

Thank you

tan(46°)   = 250 / d   rearrange

 

d = 250 / tan(46°)  = about 241 ft

 

 

 

cool cool cool
