Answer:
h = 12 m
Step-by-step explanation:
Sides of the triangle are proportional.
(3.6 m)/(1.2 m) = h/(1.2 m + 2.8 m)
(4 m)(3.6/1.2) = h . . . . . multiply by 4 m
h = 12 m
This is an arithmetic sequence, since it's pattern is +4.
n1 = 1
d = 4
n = 1 + (n-1)(4) <-------------- This is the formula for the nth term of the sequence.

<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:

Where x represents the height of the mountain
Cancel out the common units

Express as fractions

Make x the subject


Multiply

Convert the unit to feet



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