Solve for x. Show the equation you used and your work.
nasty-shy [4]
Here, You need to apply "Proportionality Theorem"
According to this theorem, the ratio of components of a leg would be equal to the ratio of corresponding components of another leg.

In mathematical form, 
AB/BD = AC/CD

Substitute their values, 
36/24 = x/18
2/3 = x/18
x = 18*3 / 2
x = 54 / 2
x = 27

In short, Your Answer would be 27

Hope this helps!

\rule{300}{1}\\\dashrightarrow\large\blue\textsf{\textbf{\underline{Given question:-}}}

      <em>Find the slope of the line that passes through (10, 7) and (3, 15).</em>

<em>Simplify your answer and write it as a proper fraction, improper fraction, or integer.</em>

<em />\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}

We can find the slope using the following formula:-

\boxed{\frac{y_2-y_1}{x_2-x_1}}

Replace the letters with numbers:-

\boxed{\frac{15-7}{3-10}}

\bigstar On simplification,

\boxed{\frac{8}{-7}}

\bigstar The slope is

\boxed{-\frac{8}{7}}

<h3>Good luck with your studies.</h3>
