Question

A 15m long ladder reached a window 9m above the ground what will be the distance from the foot of ladder to the wall​

Answer 1

Answer:

12

Step-by-step explanation:

it will form a right angle triangle

by using pythagoras theorem

hypotenuse ^2=opposite side^2+adjacent side^2

15^2=9^2+x^2

225-81=x^2

x=12

so the distance from ladder to wall is 12m

Answer 2

Answer:

Length. of ladder=15m

ht above the ground = 9m

Length, from wall to Ladder=

v15^2-9^2 =v 24x6=V144=12m
