Question

Find the missing side of the triangle.A. √337 kmB. √193 kmC. √112kmD. √5 km

Answer 1

From the given picture, we have a right triangle and we can apply Pythagorean theorem to find x, that is,

`x^2=12^2+7^2`

which gives

`\begin{gathered} x^2=144+49 \\ x^2=193 \end{gathered}`

Then, by applying square root in both side, we get

`x=\sqrt[]{193}\text{ km}`

Then, the answer is option B.
