Question

'Q8.A ladder 25m long is
placed against a wall in such a
way that the foot of the ladder
is 7 m away from the wall. Find
the height of the wall to which
the ladder reaches.​

Answer 1

Answer:

24m

Step-by-step explanation:

In right triangle ABC,

length of ladder is hypotenuse

distance between wall and ladder is base

height of wall is perpendicular

p² + b² = h²

p² + 7² = 25²

p² + 49 = 625

p² = 625 - 49

p = √576

p = 24

Therefore height of wall is 24m
