What is the length of the hypotenuse of the triangle?

Answer:
[tex]\sqrt{58}[/tex]
Step-by-step explanation:
To find the hypotenuse, we need to use the pythagorean theorem which is [tex]a^2+b^2=c^2[/tex]
[tex]3^2+7^2=c^2[/tex]
[tex]9+49=c^2[/tex]
[tex]58=c^2[/tex]
[tex]\sqrt{58} =c^2[/tex]
Hope this helps
