A bricklayer supports a 5 meter ladder. Against a vertical wall. The foot of ther ladder is 3 meters from the wall. Calculate the heigth at which the top of ladder is

4 meters

Step-by-step explanation:

Let the height at which the top of the ladder is be represented by h. The sketch of the question forms a right angled triangle. So that applying the Pythagoras rule,

= +

= +

25 = + 9

= 25 - 9

   = 16

⇒ h =

      = 4

Therefore, the height at which the top of ladder is placed is 4 meters.
