Question

What is the length of the missing side of the triangle? Round to the nearest 10th of necessary. The missing side is about blank centimeters long?

Answer 1

The triangle is a right triangle.

The unknown side is the hypotenuse. The length of the hypotenuse is calculated to be:

`c=\sqrt[]{a^2+b^2}`

where a and b are the other two sides.

Therefore, the unknown side is calculated to be:

`\begin{gathered} a=6.4 \\ b=3.5 \\ c=\sqrt[]{6.4^2+3.5^2} \\ c=\sqrt[]{40.96+12.25} \\ c=\sqrt[]{53.21} \\ c\approx7.3 \end{gathered}`

The missing side is about 7.3 cm long.
