Question

If the lengths of the legs of a right triangle are 4 and 8, what is the length of the hypotenuse?A. 32B. 4√5C. 4√3D. 12

Answer 1

Legs of a right angle triangle are perpendicular and base.

The length of a parpendicular is 4 and the length of the base is considered 8.

By Pythagoras theorem,

`\begin{gathered} H^2=P^2+B^2 \\ H^2=4^2+8^2 \\ H^2=16+64^{} \\ H^2=80 \\ H=4\sqrt[]{5} \end{gathered}`

Hence, the correct option is (B)
