The mirror is 5 feet in front of him and is approximately 40 feet from the base of the mountain. ∆ Jackson is 6’4” tall. Approxi
likoan [24]

The height of the top of the mountain is 50.67 feet

<h3>The mirror</h3>

Jackson placing the mirror in front of him will result in relations that have equivalent ratios.

<h3>Equivalent ratios</h3>

So, the equivalent ratios are represented as:

5\ ft : 40 \ ft= 6'4" : x

Where x represents the height of the mountain

Cancel out the common units

5 : 40= 6'4" : x

Express as fractions

\frac{5 }{ 40}= \frac{6'4" }{ x}

Make x the subject

x = 6'4" \times \frac{40}{5}

x = 6'4" \times 8

Multiply

x = 48'\ 32"

Convert the unit to feet

x = 48' + \frac{32}{12}'

x = 48' + 2.67'

x = 50.67'

Hence, the height of the top of the mountain is 50.67 feet
