Answer 1

Each one is multiplied by 5.
What is multiplied by 5 to get 15?

Answer 2

Can you name two sides, one of the small triangle and one of the big triangle whose mlengths you know?

Answer 3

3x5

Answer 4

So x=?

Answer 5

The side that measurs 5 in the left polygon corresponds to the side that measures 25 in the right polygon. This gives you a ratio of:

\( \dfrac{left ~polygon ~length}{right ~polygon ~length} = \dfrac{5}{25} \)

Now write a similar ratio for the unknown side, x, and its corresponding side:

\( \dfrac{left ~polygon ~length}{right ~polygon ~length} = \dfrac{5}{25} =
\dfrac{x}{15} \)

Now solve the proportion for x. Start by cross multiplying:

\( \dfrac{5}{25} = \dfrac{x}{15} \)
