Marco would like to hang a banner over his shoe store. He has two ladders and would like to know how high above the ground each ladder will allow him to place the banner. A 13- foot ladder leans against the building and touches it at a point that is 11.3 feet above the ground. what height would a 15-foot ladder touch the building if both ladders form the same angle with the ground? Make a sketch and round your answer to the nearest tenth
