Question

The height of the water tank is 8.4m. A ladder is placed against the water tank. A repairman wants to reach at a height of 5.4m on the water tank by placing a supporter EC parallel to the ground. If the distance covered on a ladder is 7.2m, find how much distance is required to reach the top of the ladder.​

Answer 1

Answer:

4.0 m

Step-by-step explanation:

Let the required distance be x

By using Ratio and proportion, we get

7.2 / 7.2 + x = 5.4 / 8.4

5.4 x + 38.88 = 60.48

5.4 x = 21.6

      x = 21.6 / 5.4

      x = 4.0 m
