A ladder is placed along a wall of a house such that its upper end is touching the top of the wall. The foot of the ladder is 2 m away from the wall and the ladder is making an angle of 60∘ with the level of the ground. Determine the height of the wall.
Let AB be the wall of height h m and C be the points, makes an angle 60° and foot of the ladder is 2m away from the wall. We have to find height of wall
In a triangle ABC, given that BC = 2m and angle C = 60°
Now we have to find the height of wall.
So we use trigonometrically ratios.
In a triangle ABC,
Hence height of wall is 2√ meters.
