Chapter 0.8, Problem 3E

To determine

To evaluate: the missing measure in the right angle triangle.

Answer to Problem 3E

The length of missing measure is 8. 31cm .

Explanation of Solution

Given information :

Diagram is given in the problem.

The diagram is given in the question,

  

Applying Pythagoras theorem,

So,

  $\begin{array}{l}{\left(10cm\right)}^2+{\left(\text{b c}m\right)}^2={\left(13cm\right)}^2\\ b^2=169-100\\ b^2=69\\ b=8.31cm\end{array}$

So,

The length of missing measure is 8. 31cm .
