Answer 1

Hey mate!

That's the answer!

Hope it helps :)

Answer 2

Answer:

= 9.2 m

Step-by-step explanation:

Let AB be the wall and BC be the ladder. Then,

∠ACB = 60° and AC = 4.6 m

  In ΔACB, cos 60° = $\frac{AC}{AB} = \frac{1}{2} = \frac{4.6}{BC}$

            =>      BC = (4.6 × 2) m

                    = 9.2 m

Good luck !!
