Answer:
DC=30
CM=15
Step-by-step explanation:
Given
Triangle DEF with C centroid
DM=45 (length of median)
centroid divides median in the ratio 2:1(larger side at vertex)
⇒
DC
⇒DC=30
DC+ CM=DM
30+CM=45
⇒CM=15

Answer:
(5.5, -3.5)
Step-by-step explanation:
As you can see in the figure, the fourth vertex is (5.5, -3.5)
If you observe carefully the vertex given, you will see that there are two vertex with same coordinates in x axis:
- (-1.2, -3.5),
- (-1.2, 4.4),
And one vertex has other coordinate in x axis, it is: (5.5, 4.4)
To form a rectangle, you need a fourth vertex that will have same coordinate in x than (5.5, 4.4) and same coordinate in y axis as (-1.2, -3.5),
Then the fourth vertex coordinate is (5.5, -3.5)
