How do I solve for x
skad [1K]

Answer:

<h3>x = 40/7</h3>

Step-by-step explanation:

Look at the picture.

If ABC is any triangle and AD bisects (cuts in half) the angle BAC, then

\dfrac{AB}{BD}=\dfrac{AC}{DC}

In our triangle we have the proportion:

\dfrac{x}{8}=\dfrac{10-x}{6}            <em>cross multiply</em>

6x=8(10-x)               <em>use distributive property</em>

6x=(8)(10)+(8)(-x)

6x=80-8x                   <em>add 8x to both sides</em>

14x=80            <em>divide both sides by 14</em>

x=\dfrac{80}{14}

\boxed{x=\dfrac{40}{7}}
