Question

Please Help! :) Solve for X. The polygons in each pair are similar.

Answer 1

Answer:

x=2.65

Step-by-step explanation:

First, we need to figure out how much the length of the sides is changing between the equations. In this case it is changing by a factor of 2.5. Now we need to work backwards. First use this equation:

$4x-5*2.5=14$

This is because whatever the length of the side with x is, will be 14/2.5. So divide both sides by 2.5:

$4x-5=5.6$

Next, add 5 to both sides:

$4x=10.6$

Then divide both sides by 4:

$x=2.65$
