Answer:

Sum of their present ages  = 20 years

Step-by-step explanation:

Present age :

   Neha's age = x years

Reemas' age = x - 4

After 5 years:

       Neha's age = (x +5) years

       Reemas' age = (x - 4 + 5 ) = x + 1

Sum of the ages of Reema and Neha will be 30

Therefore,    

x + 5  + x + 1 = 30

x + x + 5 + 1 = 30

   2x +  6    = 30

            2x = 30 - 6

           2x = 24

             x = 24/2

            x = 12

Neha's age = 12 years

Reema's age = 12 - 4 = 8 years

Sum of their present ages = 12 + 8 = 20 years

Given the diagram below what is the length of segment EF
frosja888 [35]

Answer:

C is the closest.,

Step-by-step explanation:

I am assuming that the 2 trapezoids CBEF and EFDA are similar (they are similar if the 3 horizontal lines are parallel).

Corresponding sides are in the same ratio , so:

3.4 / EF = EF / 7.6

EF^2 = 3.4 * 7.6 =  25.84

EF = 5.08
