Answer:

<em>BC is 22.5 mi</em>

Step-by-step explanation:

Using the pythagorean theorem formula. <em> </em><em>c</em><em>²</em><em> </em><em>=</em><em> </em><em>a</em><em>²</em><em> </em><em>+</em><em> </em><em>b</em><em>²</em>

<em>BC²</em><em> </em><em>=</em><em> </em><em>AB²</em><em> </em><em>+</em><em> </em><em>AC</em><em>²</em>

<em>BC²</em><em> </em><em>=</em><em> </em><em>1</em><em>9</em><em>²</em><em> </em><em>+</em><em> </em><em>1</em><em>2</em><em>²</em>

<em>BC²</em><em> </em><em>=</em><em> </em><em>3</em><em>6</em><em>1</em><em> </em><em>+</em><em> </em><em>1</em><em>4</em><em>4</em>

<em>BC²</em><em> </em><em>=</em><em> </em><em>5</em><em>0</em><em>5</em>

<em>√</em><em>B</em><em>C</em><em>²</em><em> </em><em>=</em><em> </em><em>√</em><em>5</em><em>0</em><em>5</em>

<em>BC</em><em> </em><em>=</em><em> </em><em>2</em><em>2</em><em>.</em><em>5</em>

<em>Therefore</em><em> </em><em>BC </em><em>is </em><em>2</em><em>2</em><em>.</em><em>5</em><em> </em><em>mi</em>
