Question

A ladder leans against a vertical wall. The top of the ladder is 8 m above the ground. When the bottom of the ladder is moved 2 m farther away from the wall, the top of the ladder rests against the foot of the wall. What is the length of the ladder?

Answer 1

Answer:

wall height is 8m

distance from wall to ladder is 2m

then now will height is 6m

then

6square+2square

=6*6+2*2

=36+4

=40

Answer 2

Step-by-step explanation:

Height = 8 m

let the base be X m

then,the length of the ladder will be X+2 m

According to the formula,

8^2 + X^2 = (X+2)^2
