Question

a leader is placed against a wall in such a way that it's foot is at distance of 9m from the wall and it's top reaches a window 12m above the ground in the wall find the length of the ledder. ​

Answer 1

height of the wall ==> 12m

Distance from the ladder to the wall =9m

(12)^2 + (9)^2==> (x)^2

144 + 81 ==>(x)^2

225==>x^2

15=x

Height of ladder = 15 m

Hope it helps u mark as brainliest please

Answer 2

Hey mate...

here's the answer...

Height of wall = 12m

Distance from the ladder to wall = 9m

(12)^2 + (9)^2 = (x)^2

144 + 81 = (x)^2

225 = x^2

15 = x

Height of ladder

= 15 m
