Question

A ladder 17m long rests against a vertical wall. if the foot of the ladder is 8m from the foot of the wall, find the distance of the other end of the ladder from the ground​

Answer 1

a² + b² = c²

a² + 8² = 17²

a² = 17² - 8²

a² = 225

a = √225

a = 15 m

a² + b² = c²

a² + 15² = 17²

a² = 17² - 15²

a² = 64

a = √64

a = 8 m

Width = 15 + 8 = 23

Answer 2

Answer:

A ladder 17m long rests aginst a vertical wall. If the foot of the ladder is 8m from the foot of the wall, find the distance of the other end of the ladder from the ground.
