Question

BD=16 and ÁT is the
perpendicular bisector of BD. Y=?

Answer 1

`y= 5`

Explanation:

Given

`BD = 16`

`BC = 2y - 2`

`CD = y + 3`

Required

Find y

`BD = BC + CD`

So, the expression becomes

`16 = 2y - 2 + y + 3`

Collect like terms

`16 = 2y + y- 2 + 3`

`16 = 3y+1`

Collect like terms

`3y = 16 - 1`

`3y = 15`

Make y the subject

`y= 15/3`

`y= 5`
