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?
Answered by drwls
Think about the Pythagorean theorem. The ladder length is the hypotenuse.
Answered by Christina
Okay.. whats the Pythagorean theorem again?
Answered by drwls
a^2 + b^2 = c^2
c is the hypotenuse and a and b are the perpendicular sides of a right triangle
Answered by Christina
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?
