Step 1: Do the prime factorisation of 5400

5400=2 x 2 x 2 x 3 x 3 x 3 x 5 x 5=2^3 x 3^3 x 5^2

As we can see 5, 5 are every

extra so 5400 should be divided by 5 x 5=25 to make it a perfect cube.

Answer 2

Answer:

Given:

We have been given that the height of a building is 7m

The angle of elevation of the top of a cable tove is 60° and the angle of depression of its foot is 45º.

To Find:

We need to find the height of tower.

Solution:

Let BD be the cable tove and AE be the building.

Now, we need to find BD.

AE = CD = 7m

Let BC = x

Hence, the height of tower is

7(√3 + 1)m
