Question

If the distance from point A to point C is approximately 7.2 units, then what is the approximate distance from point B to point C? 52 4 6 7.2

Answer 1

Answer

Using Pythagorean theorem

$\begin{gathered} BC^2=DB^2+DC^2 \\ BC^2=4^2+6^2 \\ BC^2=16+36 \\ BC^2=52 \\ BC=\sqrt[]{52} \\ BC=7.211 \\ BC=7.2 \end{gathered}$

The final answer

Option D
