Question

if a 15 M long ladder reached window of 12 m height from the ground on placing it against a wall at a distance x meter. find x.

Answer 1

Answer:  9 m

Step-by-step explanation:

ladder=15 m

window height=12 m

the ladder,the wall and the ground form a triangle.

in the triangle,

12^2 + x^2 = 15^2

144+x^2 = 225

x^2 = 225 - 144

x^2 = 81

x = 9 m

thus,

the ladder was resting on the ground 9 m away from the wall.

hope it helps you!
