Question

Pls help I really don’t get it

Answer 1

x = 9

Explanation:

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

`\therefore (AB)/(AD) = (BC)/(DE).... (csst)`

`\therefore (28)/(20) = (2x+3)/(15)`

`\therefore (7)/(5) = (2x+3)/(15)`

`5(2x+3) = 7* 15`

`10x+15 = 105`

`10x = 105-15`

`10x = 90`

`x = \frac {90}{10}`

`x = 9`
