5) right triangle pythagorean theorem    ladder is hypotenuse  5 m is one leg ...find other leg

6^2 = 5^2 + d^2

d^2 = 6^2 - 5^2        d = ____________  m

6.)   Pythag theorem again    hypotenuse = 8    one leg = 2    looking for other leg

8^2 = 2^2 + d^2

d^2 = 8^2  - 2^2          d = _______________  m

That can't be right.....THAT answer is longer than the hypotenuse ! Back to the chalkboard......

d2   = 11 meters    you'll need to take the square root to find   d = sqrt (11)
