A ladder is leaning against a building so that the distance from the ground to the top of the latter is 1 foot less than the length of the latter find the length of the latter if the distance from the bottom of the ladder to the building is 9 feet

ladder is leaning against a building so that the distance from the ground to the top of the latter is 1 foot less than the length of the latter find the length of the latter if the distance from the bottom of the ladder to the building is 9 feet

Step-by-step explanation:

Let :

Length of ladder = l

Height = l - 1

distance from the bottom of the ladder to the building, d = 9 feets

Lenght of ladder = hypotenus

l² = height² + distance²

l² = (l - 1)² + 9²

l² = l² + 1 + 9²

l² = l² + 1 + 81

l² = l² + 82

its c or d   take a lucky guess my dude

what is the question?
