Question

A ladder 17m long reaches a window which is 8m above the ground ,on one side of the street .keeping its foot at the same point ,the ladder is turned to the other side of the street to reach a roof at a height of 15 m .find the width of the street

Answer 1

Find the first distance :

a² + b² = c²

a² + 8² = 17²

a² = 17² - 8²

a² = 225

a = √225

a = 15 m

Find the second distance :

a² + b² = c²

a² + 15² = 17²

a² = 17² - 15²

a² = 64

a = √64

a = 8 m

Find the width of the street:

Width = 15 + 8 = 23 m

Answer: The width of the street is 23 m
