Question

a ladder 10m, is placed to a distance of 8m from the wall. At what height will it reach the wall?​

Answer 1

Answer:

6m

Step-by-step explanation:

it is of course obvious that the wall touches the ground at a 90° angle

so in any case it will form a right triangle

hyp=10m

base=8m

by pythagoras theorem we get

10²=8² + h²

100=64 + h²

h²=100-64=36

h=√36=6m
