Given:
The objective is to find the hypotenuse c of the right triangle.
Consider the right triangle as,
The length of the side c can be calculated using Pythagoras theorem.
[tex]\begin{gathered} AB^2=AC^2+BC^2 \\ c^2=36^2+15^2 \\ c^2=1296+225 \\ c^2=1518 \\ c=\sqrt[]{1518} \\ c=38.96 \\ c\approx39 \end{gathered}[/tex]
Hence, option (B) is the correct answere.
