Question

The top of a 15m long ladder reaches a window 9m high from the ground. Find the distance between the foot of ladder and the wall​

Answer 1

Step-by-step explanation:

By pythagoras theorem,

hypotenuse=15m

one side=9m

base=? let base be x.

$15^{2}$=$9^{2}$+$x^{2}$

225=81+$x^{2}$

225-81=$x^{2}$

144=$x^{2}$

$\sqrt{144}$=x

12=x

Therefore,distance between foot of ladder and wall=12m

Hope it helps
