Here, AC is a length of ladder.

Here, AC is a length of ladder.⇒ BC=9.5m

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o =

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = AC

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ=

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ= Hypotenuse

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ= HypotenuseAdjacentside

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ= HypotenuseAdjacentside

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ= HypotenuseAdjacentside ]

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ= HypotenuseAdjacentside ]⇒

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ= HypotenuseAdjacentside ]⇒ 2

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ= HypotenuseAdjacentside ]⇒ 21

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ= HypotenuseAdjacentside ]⇒ 21

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ= HypotenuseAdjacentside ]⇒ 21 =

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ= HypotenuseAdjacentside ]⇒ 21 = AC

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ= HypotenuseAdjacentside ]⇒ 21 = AC9.5

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ= HypotenuseAdjacentside ]⇒ 21 = AC9.5

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ= HypotenuseAdjacentside ]⇒ 21 = AC9.5

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ= HypotenuseAdjacentside ]⇒ 21 = AC9.5 ∴ AC=9.5×2

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ= HypotenuseAdjacentside ]⇒ 21 = AC9.5 ∴ AC=9.5×2∴ AC=19m

Here, AC is a length of ladder.⇒ BC=9.5m⇒ Now, cos60 o = ACBC [ cosθ= HypotenuseAdjacentside ]⇒ 21 = AC9.5 ∴ AC=9.5×2∴ AC=19m∴ Length of the ladder is 19m.
