Best ResponseYou've already chosen the best response.0Use the Pythagorean theorem for this. a^2+b^2=c^2 The ladder is c The wall is b The ground is a Rearrange the equation so that you can solve for a. a^2=c^2b^2 Substitute values. a^2=32^2+23^2 Simplify a^2=1024529 a^2=495 Square both sides. √a^2=√495=22.2 Answer: 22.2
