Answer 1

The flagpole is 51ft tall

Explanation:

Given

See attachment for flagpole

Required

The height of the flagpole

To do this, we use the following equivalent ratios

`h : 85 = 6 :10`

Where h is the required height

Express as fraction

`(h)/( 85) = (6 )/(10)`

Make h the subject

`h = (6 )/(10) * 85`

`h = (6 * 85)/(10)`

`h = (510)/(10)`

`h = 51`
