Jackies kitten is stuck on the window sill of her neighbors house. The window is 2.8m above the ground. The base of the ladder must be 0.7m away from the house and the ladder must extend 1m above the window sill. Will she be able to rescue the kitten, explain how..
That depends upon the length of the ladder. You can figure out the minimum length of the ladder with this formula -- where 3.8 is a and 0.7 is b and c is the length of the ladder.
a^2 + b^2 = c^2
