Question 881088
	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?
:
let d = dist to the building
Use the tangent of the angle of 38, where side op = 300; side adjacent = d
tan(38) = {{{300/d}}}
.7813 = {{{300/d}}}
mult by both sides by d
.7813d = 300
d = {{{300/.7813}}}
d = 384 ft
