Question

A ladder 25 feet long is leaning against a wall that is perpendicular to the ground. If the foot of the ladder is 7 feet from the base of the wall, find the height of the point at which the ladder touches the wall.​

Answer 1

Answer:

Hypotenuse square = perpendicular square + base square

25 square = 7 square + perpendicular square

625 = 49 + perpendicular square

625 - 49 = perpendicular square

576 = perpendicular square

under root 576 = perpendicular

24 = perpendicular

Hence perpendicular= 24 feet

Answer 2

Answer:

Hypotenuse square = perpendicular square + base square

25 square = 7 square + perpendicular square

625 = 49 + perpendicular square

625 - 49 = perpendicular square

576 = perpendicular square

under root 576 = perpendicular

24 = perpendicular

Hence perpendicular= 24 feet
