ANSWER
17
EXPLANATION
We wamt to find the value of x in the figure.
To do that, we have to apply Pythagorean theorem:
[tex]\begin{gathered} \text{hyp}^2=a^2+b^2 \\ \text{where a and b are legs of the triangle} \\ \text{hyp = hypotenuse} \end{gathered}[/tex]
Therefore, we have that:
[tex]\begin{gathered} x^2=8^2+15^2 \\ x^2=64+225 \\ x^2=289 \\ \Rightarrow x=\sqrt[]{289} \\ x=17 \end{gathered}[/tex]
That is the answer.
