Question

32. A ladder is placed in such a way that its foot is 15 m away from the wall and its top reaches a
window 20 m above the ground. The length of the ladder is
33. The hypotenuse of a right triangle is 26 cm long. If one of the remaining two sides is 10 cm
long, the length of the other side is
34. A 15 m long ladder is placed against a wall in such away that the foot of the ladder is 9 maw
from the wall. Up to what height does the ladder reach the wall?
​

Answer 1

Step-by-step explanation:

Let the height of the window from the ground and the distance of the foot of the ladder from the wall be AB and BC, respectively.  We have :  AB = 20 m and BC = 15 m  Applying Pythagoras theorem in right-angled ABC, we get: Hence, the length of the ladder is 25 m. 

Answer 2

Answer:

Let ABC be a triangle where height of wall is AB=?and AC be length of ladder =15m and BC be distance between ladder and wall.

Step-by-step explanation:

Now by pythagoras theorem

Ac^2=AB^2+BC^2

15^2=AB^2+9^2

225=AB^2+81

AB^2=225-81

AB=✓144cm

AB=12cm
