Set this up as a proportion $$\huge \frac{18}{10} =\frac{x}{5}$$ Now just solve for x

3. anonymous

What is the value of x in the equation I gave you?

4. anonymous

In similar triangles, the ratios of corresponding sides are equal. Therefore, $\frac{ x }{ 18 }=\frac{ 5 }{ 10 }$ Solve for x

5. anonymous

yeah breanna solve for x

6. anonymous
