Question

Can anyone help me? again, im not really good at solving these things. ​

Answer 1

`√(14)`

Step-by-step explanation:

The triangles are similar so ratios of corresponding sides are equal, that is

`(y)/(2)` =
`(7)/(y)` ( cross- multiply )

y² = 14 ( take the square root of both sides )

y =
`√(14)`
