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?

  • Geometry -

    Think about the Pythagorean theorem. The ladder length is the hypotenuse.

  • Geometry -

    Okay.. whats the Pythagorean theorem again?

  • Geometry -

    a^2 + b^2 = c^2
    c is the hypotenuse and a and b are the perpendicular sides of a right triangle

  • Geometry -

    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?

  • Geometry -

    yep
