Answer:

x = 9

Step-by-step explanation:

\triangle ABC\sim \triangle ADE.... (given)

\therefore \frac{AB}{AD} = \frac{BC}{DE}.... (csst)

\therefore \frac{28}{20} = \frac{2x+3}{15}

\therefore \frac{7}{5} = \frac{2x+3}{15}

5(2x+3) = 7\times 15

10x+15 = 105

10x = 105-15

10x = 90

x = \frac {90}{10}

x = 9
