Question

Find the unknown side length on the triangle below to the nearest tenth

Answer 1

The triangle from this problem is a right triangle. This means that we can use Pythagora's Theorem to find the unkown side. This is done below:

`\begin{gathered} \text{Hypothenuse}^2=side1^2+side2^2 \\ 14^2=7^2+side2^2 \\ \text{side}2^2=14^2-7^2 \\ \text{side}2^2=196-49=147 \\ \text{side}2=\sqrt[]{147}=12.1 \end{gathered}`

The missing side has a length of 12.1
