ad , bd , and cd are angle bisectors of the sides of △abc . be=12 m and bd=20 m.

what is dg ?

The answer is 16

And also , can people please stop posting did you get the answer yet, just so you could get the  points.  They only take two answers, and that's a waste of somebody who could've answered or helped.

DG=16 m

Step-by-step explanation:

Given: AD, BD and Cd are the angle bisectors of the sides of ΔABC and B=12m and BD=20m.

To find: The value of DG.

Solution: It is given that AD, BD and Cd are the angle bisectors of the sides of ΔABC and B=12m and BD=20m, then from the ΔBED, we have

Substituting the given values, we have

Thus, the value of ED is 16m.

Now, we know that the distance from the mid points of the sides of the given triangle to the circumcenter D are equal, thus

ED=DG

ED=DG=16

Therefore, the value of DG is 16m.
