Answer 1

Explanation:

Answer 2

x = 10

Explanation:

Since the triangles are similar the ratios of corresponding sides are equal

`(20)/(20+8)` =
`(3x)/(4x+2)`, that is

`(20)/(28)` =
`(3x)/(4x+2)` ( cross- multiply )

20(4x + 2) = 84x

80x + 40 = 84x ( subtract 80x from both sides )

40 = 4x ( divide both sides by 4 )

x = 10
