If the bottom of the ladder is 9 meters away from the building, how high can a 15 meter long ladder reach the building______ Rice
∵ the length of the oblique side of the right triangle is 15m, the length of one right side is 9m, and the length of the other right side = 152 − 92 = 12M, so the height of the ladder to reach the building is 12m
If the bottom of the ladder is 9m away from the bottom of the building, the height that a 15m long ladder can reach the building is (can you do the figure below)
Calculate the Pythagorean theorem
Height = (15 ^ - 9 ^ 2) ^ 0.5 = 12
