I really need some help..Please? http://gyazo.com/64afdd886cf5332585b1cc1d7eb0cce7

OpenStudy (anonymous):

@Mertsj Could you maybe help some? I really need to figure this out.

OpenStudy (mertsj):

The ratios of the corresponding sides are equal.

OpenStudy (anonymous):

Uh-- Okay?

OpenStudy (anonymous):

How do I go about it from that?

OpenStudy (mertsj):

Write the ratios, put an equal sign between them and solve the proportion.

OpenStudy (anonymous):

I don't know how to do that, but thank you.

OpenStudy (mertsj):

Do you know what a ratio is?

OpenStudy (anonymous):

Yeah, I think.

OpenStudy (mertsj):

Do you know what corresponding sides are?

OpenStudy (anonymous):

Is it like..They're the same thing?

OpenStudy (mertsj):

It means they occupy corresponding positions in the two triangles.

OpenStudy (mertsj):

In your picture x corresponds to 11.2 so the ratio is x over 11.2

OpenStudy (anonymous):

Okay..

OpenStudy (mertsj):

Then write the ratio of the other two corresponding sides. What is it?

OpenStudy (anonymous):

5.4:6.3?

OpenStudy (mertsj):

put an equal sign between those two ratios and solve for x

OpenStudy (mertsj):

\[\frac{x}{11.2}=\frac{5.4}{6.3}\]

OpenStudy (anonymous):

Okay. How would I solve for x?

OpenStudy (mertsj):

Cross multiply
