Question

Could someone help with this geometry question?
The polygons are similar, but not necessarily drawn to scale. Find the value of x.

Answer 1

First step should be to find the value of the side that is equal to x-3 so find the factor between the corresponding sides of the polygons

Answer 2

Its 2.5 right?

Answer 3

What?

Answer 4

I mean the ratio between the corresponding sides of the polygons so from 2->8 and 4->16

Answer 5

Oh oops you mean in the same polygon? so it would be 8?..

Answer 6

What I mean is that, the first polygon is 4 times as large as the second. You can figure that out by comparing corresponding sides between both figures.

Answer 7

Oh. so all I would need to go is times 2.5 by the same ratio which would be by 4, and that would give me the answer?

Answer 8

No, that would give you the value for x-3 so basically add 3 to 2.5*4 and that is your answer :)

Answer 9

Oh ok that makes sense. Thanks!

Answer 10

No problem :)
