Question

Find the value of y.

Answer 1

`√(55)`

Explanation:

∆ BCD ~ ∆ DCA

`(bc)/(dc) = (dc)/(ac)`

Plug the values:

`(5)/(y) = (y)/(6 + 5)`

`(5)/(y) = ( y)/(11)`

Apply cross product property

`y * y = 11 * 5`

Calculate the product

`{y}^(2) = 55`

`y = √(55)`

Hope this helps...

Good luck on your assignment..
