Question

8. A 26 m long ladder reaches a window 24 m high from the ground on
placing it against the wall. How far is the foot of the ladder from the wall?​

Answer 1

Answer:

5

Step-by-step explanation:

Through pythagerous theorum, the length of the ladder can be taken as hypotenuse

26^2=24^2+x^2 (pythagerous theorum)

26*2-/24*24=x^2

13*13-12*12=x^2

169-144=x^2

25=x^2

sqroot of 25= x

5=x
