Answer:

x = 5/4

y = 7/4

Step-by-step explanation:

The smaller triangle and the larger one are similar, so the sides are proportional.

(x+5)/5 = 10/8

x/5 + 1 = 1/4 + 1 . . . . . divide it out

x/5 = 1/4 . . . . . . . . . . .subtract 1

x = 5/4 . . . . . . . . . . . . multiply by 5

___

For y, you can do exactly the same computations, replacing every instance of 5 with a 7. Then you get ...

y = 7/4

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
