Question

PLEASE HELP Find
y, such that ABC ~ DEF.

Answer 1

`y =12`

Explanation:

Given

ABC similar to DEF

Required

Find y

To do this, we make use of the following equivalent ratios.

`AB : AC = DE : DF`

Using the values in the attachment, we have:

`9 : 18 = 6 : y`

Express as fraction

`(9 )/( 18 )= (6 )/( y)`

`(1 )/(2 )= (6 )/( y)`

Solve for y

`y = 6 * 2`

`y =12`
