Question

a ladder 10m long rest against a vertical wall, if the foot of the ladder is 6m long away from the wall and the ladder just reaches the top of the wall,how high the wall? ​

Answer 1

Answer:

Height of the ladder for the given problem is 8m

Answer 2

ladder is hypotenuse 10m

the foot of the ladder is 6m long away from the wall BASE

By Pythagoras theorem

H² =P² +B²

10² = P² + 6²

P² = 100-36 = 64

P= 8m

high the wall 8m
