Question

Find the missing length of the triangle 8.5 m a 7.5 m The missing length is meters.

Answer 1

Since it is a right triangle, we can use pythagorean theorem:

`\begin{gathered} c^2=a^2+b^2 \\ where \\ c>a,c>b \\ Let \\ c=8.5m \\ b=7.5m \end{gathered}`

So:

`\begin{gathered} 8.5^2=a^2+7.5^2 \\ a=\sqrt[]{8.5^2-7.5^2} \\ a=\sqrt[]{72.25-56.25} \\ a=\sqrt[]{16} \\ a=4m \end{gathered}`
