Question

A ladder is inclined against a wall 15 feet high. Find how far away the foot of the ladder is from the wall.

Answer 1

Step-by-step explanation:

From figure,

Let the distance from foot of the ladder to the wall be x

AOB is an right angle triangle,

So, 17^2 = 15^2 + x^2

⟹ x^2 = 289 - 225

⟹x^2 = 64

⟹x = 8m
