c = ___ft. I WILL MARK BRAINLIEST!!!!!!!!!!!! this is a quiz so i need it fast

Using Pythagorean theorem
[tex]\\ \sf\longmapsto H^2=P^2+B^2[/tex]
[tex]\\ \sf\longmapsto c^2=6^2+8^2[/tex]
[tex]\\ \sf\longmapsto c^2=36+64[/tex]
[tex]\\ \sf\longmapsto c^2=100[/tex]
[tex]\\ \sf\longmapsto c=\sqrt{100}[/tex]
[tex]\\ \sf\longmapsto c=10ft[/tex]
