Question

A 10m long ladder leans in a wall. The foot of the ladder is 6m away from the wall. How high is the top of the ladder from the floor. Answer plz

Answer 1

Ladder leans against the wall so it forms a right angled triangle

hypotenuse = 10m

base = 6 m

height = √10² - 6²

= √100 - 36

= √64

= 8m
