Question

6) What is the length of side x?

Answer 1

The given triangle is a right angled triangle. Therefore, by Pythagoras theoram,

`\text{hypo}^2=base^2+altitude^2`

From the figure,

`\begin{gathered} x^2=2^2+5^2 \\ x^2=29 \\ x=\sqrt[]{29} \end{gathered}`

Hence, Option D is the right answer.
