7. A 3.6 m ladder is leaning against a wall, with its base 2 m from the wall. a) Draw a scale diagram to represent this situation. b) Suppose that a 2.4 m ladder is placed against the wall, parallel to the longer ladder. Explain why the triangles that are formed by the ground, the wall, and the two ladders are similar. c) How far up the wall will each ladder reach?
