Question

If DM = 25, what is the value of r?

Answer 1

Answer:

$r=\dfrac{31}{3}$

Step-by-step explanation:

The problem says that G is any point lying on line segment DM. So,

DG = GM

We have, DG = and GM = 4r-28

Putting values in above equation

r +3 = 4r-28

Taking like terms together

r-4r = -28-3

-3r = -31

$r=\dfrac{31}{3}$

So, the value of r is $\dfrac{31}{3}$
