Question

In the accompanying diagram of right triangle ABC, AB = 4 and BC 7. What is the length of Ac to the weares hundredth?

Answer 1

In order to calculate the length of AC, since we have a right triagle, we can use the Pythagorean theorem:

$\begin{gathered} AC^2=AB^2+BC^2 \\ AC^2=4^2+7^2 \\ AC^2=16+49 \\ AC^2=65 \\ AC=\sqrt[]{65}=8.06 \end{gathered}$

So the correct option is C.
