hypotenuse
=sqrt[3^2+8^2]
=sqrt 73
=8.544 cm

Pythagorean Theorem: a^2 + b^2 = c^2
3^2 + 8^2 = c^2
9 + 64 = c^2
c = sqrt(73) cm

hypotenuse= sqrt(3*3+8*8)= sqrt(9+64)= sqrt(73)= 8.544003

using Pithagoras
c^2= a^2+b^2
c^2= 3^2+8^2
c^2=9+64=73
c= square root(73)= 8.54

What are the answers so I can check my work.... Also, people can't answer questions that reference diagrams if you don't provide the diagrams.
