Question

What is the ninth of the missing side of the triangle rounds the nearest 10th necessary. The missing side is about blank cm

Answer 1

Given:

Base =3.5 cm

Perpendicular = 6.4 cm

Find: Hypotenuse

Sol:

Use Pythagoras theorem.

`\text{ Hypotenuse}^2=Base^2+perpendicular^2`
`\begin{gathered} \text{ Hypotenuse}^2=3.5^2+6.4^2 \\ \text{ Hypotenuse}^2=12.25+40.96 \\ \text{ Hypotenuse}^2=53.21 \\ \text{ Hypotenuse=}\sqrt[]{53.21} \\ \text{ Hypotenuse=7.2945} \end{gathered}`

So the hypotenuse is 7.3
