The angels of elevation of a ladder against a wall is 60 degree and the foot of the ladder is 4.6 m away from the wall. the length of the ladder is

The length of the ladder is 9.2 meters

Step-by-step explanation:

Given as :

The angels of elevation of a ladder against a wall = 60°

The Distance of the foot of the ladder fro the wall = d = 4.6 meters

Let The length of the ladder = h meters

Now, According to question

cos angle =

Or, cos 60° =

Or, 0.5 =

∴  h =

i.e h = 9.2

So,The length of the ladder = h = 9.2 meters

Hence The length of the ladder is 9.2 meters Answer
