If the bottom of the ladder is 9m away from the building, how many meters can a 15m long ladder reach the height of the building
This problem is the relationship between the three sides of a right triangle: the hypotenuse is 15 meters, one right side is 9 meters, and the height is the other right side,
15²-9²=225-81=144
144 square meters = 12 meters
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
