Question

Find the two dimensional diagonal. Write your answer as a radical. a= units b= 5 units c= 6 units

Answer 1

`c=\sqrt[]{61}=7.81`

Explanation:

According to the figure we can see that a right angle is formed, therefore we can apply the Pythagorean theorem

`c^2=a^2+b^2`

replacing we have

`\begin{gathered} c^2=5^2+6^2 \\ c^2=25+36 \\ c=\sqrt[]{61}=7.81 \end{gathered}`
