Question

66. Find the length of the missing side. Drawing not to scale.8A. 48B. 28C. 100D. 10

Answer 1

The three sides of a right-angled triangle follow the Pythagoras theorem, i.e

`\text{Hypothenus}^2=opposite^2+adjacent^2`

From the given triangle,

`\begin{gathered} \text{opposite = 6} \\ \text{adjacent = 8} \\ \text{hypothenus = ?} \end{gathered}`

Using the theorem, we can obtain the length of the missing side:

`\begin{gathered} \text{Hypothenus}^2=6^2+8^2 \\ \text{Hypothenus =}\sqrt[]{100} \\ =\text{ 10} \end{gathered}`

The correct option is D
