#34. if ad= 12 and ac= 4y- 36, find the value of y. then find ac and d. c.

The midpoint of a line is the point that divides the line into two equal halves. Point D divides segment AC into two equal halves.

Given that:

From the attached figure, point D is the midpoint of line segment AC, So:

This gives:

Collect like terms

Divide both sides by 4

Hence, the value of y is 15

Recall that:

Hence, the length of AC is 24

Line segment DC has the same value as AD.

Hence, the length of DC is 12
