A 9ft ladder leans against a building 6ft above the ground. At what height would a 15ft ladder touch the building if both ladders form the same angle with the ground?
I am not 100% sure but... It should probably touch the building at 10 feet. I think this because the ratio 9 to 6 is equal to 3 to 2. 3 to 2 multiplied by 5 to 5 is equal to 15 to 10.
