Question

a ladder of length 17m is placed such that it's foot is 8m far from a vertical wall of height 100m .How high the ladder can reach on the wall​

Answer 1

Answer:

15m

Step-by-step explanation:

let the height of wall till where the ladder reaches be x

length of ladder =17m

length between the foot of the wall and the foot of the ladder=8m

according to the pythagoras theorem-:

(17)²=(8)²+(x) ²

289=64+x²

289-64=x²

225=x²

√225=x

15m =x
