Question

a ladder 17 metre long reaches a window of a building 15 metre above the ground find the distance of the foot of the ladder from the building ​

Answer 1

Answer:

Height of ladder =17m

Height of building =15m

Let distance of foot of ladder from building=x m

According to pythagoras theorem

(x×x)+(15×15)=17×17

(x×x)+225=289

x×x=289-225

x×x=64

x=8

Therefore,the distance of the foot of the ladder from the building is 8 meter.
