Chapter 13.7, Problem 7PSA

To determine

To find:The measure of BD.

Answer to Problem 7PSA

The measure of BDis $\text{10}\text{unit}$ .

Explanation of Solution

The length BD is calculated as,

  $\begin{array}{c}BD=\sqrt{{\left(x_2-x_1\right)}^2+{\left(y_2-y_1\right)}^2}\\ =\sqrt{{\left(8-2\right)}^2+{\left(15-7\right)}^2}\\ =\sqrt{36+64}\\ =10\text{units}\end{array}$

Therefore, the measure of BD is $\text{10}\text{unit}$ .
