Question

The picture shows a flagpole, AB, above a house.



Rounded to the nearest whole number, what is the height, in feet, of the flagpole AB?

Answer 1

This uses basic trigonometry.

From the very top of the flagpole to the ground (From A to ground) = x
From B to ground = y
tan(60) = √3 = x/16 x=16√3
tan(45) = 1 = y/16 y=16

AB=x-y = 16√3-16= approximately 11.7

So 12.
