Question

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

Answer 1

Answer:

$y= 5$

Step-by-step 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

$y= 15/3$

$y= 5$
