An equation is shown below:

Drupady [299]

27x - 144 + 15 = 6x - 24
27x - 129 = 6x - 24
+129 +129
--------- --------
0 105
27x = 6x + 105
-6x -6x
----- ------
21x 0

21x = 105

21x/21 = 105/21

x = 5

In △ABC, DG=32 cm .

Mariana [72]

<span>In any triangle, medians are concurrent and their common intersection point divides each median in proportion 2:1, counting the median parts from the vertex. So, if DG = 32 cm, then AG = 64 cm, and the entire median AD</span>
