Question

Use the diagram to the right.

If AD = 17 and AC = 2y - 6, find the value of y. Then find AC
and DC.

Answer 1

Explanation:

Answer 2

Explanation:

if AD =17,then Dc is also 17 because from the diagram,it is given that AD=DC.

And because AD and DC are equal,it means AC = AD +DC,therefore AC = 17+17,AC =34

AC=2y-6

therefore

34=2y-6

28=2y and y=14
