Step-by-step explanation:

Our task is to find the third side of this right triangle. To do that, we'll apply the Pythagorean theorem:

[tex]\mapsto\quad\sf a^2+b^2=c^2[/tex]

where c is the hypotenuse (it's what we're looking for)

Substitute the values:

  • [tex]\sf 13^2+15^2=c^2[/tex]
  • [tex]\sf394=c^2[/tex]
  • [tex]\sf c=19.8\:cm[/tex]    Answer
