Question

and this one too Which of the following represents a Pythagorean Triple?Group of answer choices{21, 72, 75}{11, 45, 60}{5, 7, 10}{10, 20, 30}

Answer 1

17

Step-by-step explanation

We wamt to find the value of x in the figure.

To do that, we have to apply Pythagorean theorem:

`\begin{gathered} \text{hyp}^2=a^2+b^2 \\ \text{where a and b are legs of the triangle} \\ \text{hyp = hypotenuse} \end{gathered}`

Therefore, we have that:

`\begin{gathered} x^2=8^2+15^2 \\ x^2=64+225 \\ x^2=289 \\ \Rightarrow x=\sqrt[]{289} \\ x=17 \end{gathered}`

That is the answer.
