Question

a ladder is 17m long, it reaches a window at a height H above the ground.if the foot of ladder is at the distance of 8m from the wall.find the height of the window.

Answer 1

first draw a right angle triangle which ab,bc and ac

take an angle at c side opp to it is ladder which is ac is=17m and adjacent which is bc=8m distance

we need to find

thn

ATQ,

APPLY PHYTHATGORES THEOREM

AC

$ac ^{2} = ab {}^{2} + bc {}^{2}$

17

$17 {}^{2} = ab {}^{2} + 8 {}^{2}$

ab

$ab {}^{2} = 289 + 64$

$ab {}^{2} = 353$

$ab = \sqrt{353}$

ab=18.78m

Answer 2

Answer:

pls follow and thank and mark as BRAINIEST ANS

actually ans before there was one mistake that it didn't subtract ab²from ac²

steps were coorect the ans actually is 15m
