How many groups of 2/3 are in 3/5

asesadfdsasdrs

Step-by-step explanation:

To find the answer, we will need to divide 3/5 by 2/3.

3/5 / 2/3

3/5 x 3/2

9 / 10

There are 9/10 groups of 2/3 in 3/5.

Hope this helps!! :)

The length of the rectangle garden is 20 i.e 34.64 meters .

Step-by-step explanation:

Given as :

The height of the pole = H = 30 m

The two angles of elevation as 60° and 30°

Let The length of the rectangle garden = L m

Now, From figure

The measure from pole ground to first elevation 60° = x m

The measure from pole ground to second elevation 30° = (L + x ) m

Now, from triangle BOC

Tan Ф =

I.e Tan 60° =

Or, =

or, x =

I.e x = 10 meter      ...1

Again From triangle BAC

Tan Ф =

I.e Tan 30° =

Or, =

Or, L + x = 30 ×   ....2

Put the value of x from  1 into 2

i.e L + 10 meter   = 30 ×

or, L = 30 - 10  

Or, L = 20 = 34.64 meters

I.e length of garden is 20

Hence The length of the rectangle garden is 20 i.e 34.64 meters . answer
