Given:
In triangle ABC, point D is the centroid, and BD = 6.
To find:
The measure of side BE.
Solution:
We know that the centroid divides each median in 2:1.
In the given figure BE is a median and point D is the centroid. It means point D divides the segment BE in 2:1.
Let BD and DE are 2x and x respectively.
We have, BD = 6 units.
Now,
Therefore, the measure of side BE is 9 units.
Hello there! x = 66.
x/6 + 4 = 15
This means that since 15 - 4 = 11, x/6 = 11.
Given the two numbers and a variable, we can multiply:
6 x 11 = 66
66/6 = 11
Therefore, x = 66
Hope this helps!
Hello there! The lines between the numbers represent absolute value. In case you don't know, absolute value is the distance from 0, and it is always positive. For this, the absolute value of -6 is 6 and the absolute value of -0.4 is 0.4. 6 + 0.4 is 6.4. There. You chose the right answer choice. The answer is 6.4.
21*9
9 sides times 21 per side
