    3.00 m to the nearest hundredth.

    Step-by-step explanation:

    We solve this using the trigonometry of a right triangle:

    The hypotenuse = 8 m and we need the adjacent side, so:

    cos 68 = adj/hyp = x / 8 where x, the adjacent side = the distance of the ladder from wall.

    x = 8 cos 68

    = 2.997 m
