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?angel

Tan(38)= 300/B

0.7812856=300/B

B=300/.7812856

B=383.98 Feet-the distance to the base of the building.
