Let's say the sides are "a" first one, "b" second one and "c" the third one
ok, let's say the shortest is "a"
and let's say "b" is -> "<span> twice the length of the shortest side"
so b = 2a
and let's say "c" is -> "</span><span>3rd side 14 more feet than length of shortest side"
so c = a + 14
we know the perimeter ( sum of all sides ) is 154
</span>
<span>
solve for "a"</span>

Refer to the diagram below for the sketch of the position of the mirror, Michelle, and the flagpole.
Using similar triangle concept, to find the height of the flagpole, we first need to find out the scale factor of the horizontal distance.
We write this as ratio
Mirror to Michelle : Mirror to Flagpole
12ft : 48ft
1 : 4
So the ratio of the height is
Michelle : Flagpole
1 : 4
5ft : 20ft
