Question

Use the diagram below to determine the height of the flagpole.

Height of flagpole =

Scale factor from stick to flagpole =

Scale factor from flagpole to stick =

Answer 1

Height of flagpole= 12ft

Scale factor from stick to flagpole: 3:1

Scale Factor from flagpole to stick: 1:3

Explanation:

ratio from stick to shadow = ratio from flagpole to shadow

so 4:2.5

we can assume 4(3):2.5(3)

which is 12:7.5
