Question

PLZ HELP IT'S VERY IMPORTANT

The bottom of a ladder must be place 5 feet from a wall. The ladder is 13 feet long. How far above the ground does the ladder touch the wall?​

Answer 1

Explanation:

It is clear that the wall makes a right angle with the ground. Therefore, we can apply Pythagoras theorem to get its sides.

Hypotenuse ^2= altitude^2+ base^2

altitude ^2=hypotenuse^2-base^2

=13^2-5^2

=144

Altitude/the point where the ladder meets the wall = 12.(√144)
