Question

Find the missing side of this righttriangle.Х714x = V[?]Enter the number that belongs in the green box,

Answer 1

For this problem, we could use the pythagorean theorem as follows:

The pythagorean theorem states that the square of the hypotenuse equals to the sum of the square of each one of the sides of the triangle:

`\begin{gathered} x^2=7^2+14^2 \\ x^2=49+196 \\ x^2=245 \end{gathered}`

Finally,

`x=\sqrt[]{245}`

So, the number that you must put in the green box is 245.
