<h2>The length of AC is 13.67cm</h2>

<h2>Solution </h2><h2>= Here a = BC = 3 , and C = AB = 14 . </h2>

<h2> c² = a² + b² </h2><h2> 14² = 3² + b² </h2><h2> 196 = a + b²</h2><h2> b² = 196 - 9</h2><h2> = 187 </h2><h2> b = √187 = 13.67</h2><h2> The length of AC is 13.67</h2>

Answer:

Explanation:

As you can deduce from the diagram, each unit is equivalent to 1.
