Since, is the entire median and is the centroid then just like you said.Originally Posted by wpcp15
But, and
Thus, (substitute)
Now, open paranthese,
Subtract from both sides,
Subtract from both sides,
Thus, and .
In Triangle ABC, segmentS CM, BP, and AN are medians
If CM=3X+6 and CE=x+12, find the value of x. Being that e is the centroid.
I know that from the vertex to the centroid is 2/3 of the entire median, but i cant figure out what x equals
I think the value of x equals 18, but im not sure
Also, I need help answering
If EN= X-5 and AE=X+17, find the value of AN.
For the second answer.
Remember that the ratio from the vertex to the centriod to to the remaining part of the median is 2:1.
Thus,
But, and
Thus, (substitute)
Cross multiply,
Open parantheses,
Subtract from both sides,
Add 10 to both sides,
Thus, and .
