A PEICE OF ICE AT 0 DEGREE CELCIUS FALLS FROM REST INTO A LAKE OF WAYER WHICH IS ALSO AT 0 DEGREE CELCIUS AND 0.5% OF ICE MELTS.FIND M​

Answer 1

Step-by-step explanation:

✬ Distance = 6 m ✬

Step-by-step explanation:

Given:

Length of ladder is 10 m.

Length of window is 8 m.

To Find:

Distance of foot of ladder from base of wall ?

Solution: Let AC be a ladder , AB be a window and BC be the distance of between foot of ladder and base of wall.

Now in right angled triangle we have

AB = perpendicular (8 m)

AC = hypotenuse (10 m)

BC = base

∠B = 90°

Applying Pythagoras Theorem in ∆ABC

★ H² = Perpendicular² + Base² ★

\implies{\rm }⟹ 10² = 8² + b²

\implies{\rm }⟹ 10 × 10 = 8 × 8 + b²

\implies{\rm }⟹ 100 = 64 + b²

\implies{\rm }⟹ 100 – 64 = b²

\implies{\rm }⟹ 36 = b²

\implies{\rm }⟹ √36 = b

\implies{\rm }⟹ √6 × 6 = b

\implies{\rm }⟹ 6 = b

Hence, the distance between foot of ladder from base of wall is 6 m.
