If you place a 58-foot ladder against the top of a 42-foot building, how many feet will the bottom of the ladder be from the bottom of the building?
+36916 Use the pythagorean theorem
hypotenuse is the ladder 58 ft
one leg is the building side 42 ft
find the other leg
a^2 + b^2 = c^2
a^2 + 42^2 = 58^2
a^2 = 58^2-42^2
a = 40 ft
