Jack has a 35-foot ladder leaning against the side of his house. If the bottom of the ladder is 21 feet away from his house, how many feet above the ground does the ladder touch the house?

The distance above the ground does the ladder touch the house x = 28 ft

Step-by-step explanation:

Given data

Length of the ladder = AC = 35 ft

BC = 21 ft

AB = x = distance above the ground does the ladder touch the house

From Δ ABC

x = 28 ft

Therefore the distance above the ground does the ladder touch the house is x = 28 ft

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
