The foot of a ladder is placed 6 feet from a wall. If the top of the ladder is 8 feet up on the wall, how long is the ladder?

Think about the Pythagorean theorem. The ladder length is the hypotenuse.
Okay.. whats the Pythagorean theorem again?
a^2 + b^2 = c^2
c is the hypotenuse and a and b are the perpendicular sides of a right triangle
c is the hypotenuse and a and b are the perpendicular sides of a right triangle
Okay i think i got it.
a^2 + b^2 = c^2
6^2 + 8^2 = c^2
36 + 64 = c^2
sqrt of 100 = sqrt of c^2
10ft = C
Is that right?
