The angle of elevation of a ladder leaning against a wall is 45°. If the distance from the base of the ladder to the wall is 15 feet, find the length of the ladder.

  • Geometry -

    You have a 45° right triangle, so the legs are of equal length.

    The ladder forms the diagonal of a 15' square, so the length is 15√2.
