In ∆ABC, point D is the centroid. If (AE) ̅=15, (BF) ̅=27, and (CD) ̅=8, find the following lengths
Anna71 [15]

Answer:

5,18,12 cms are the answer.

Step-by-step explanation:

Given is a triangle ABC.  Point D is the centroid.  

E,F and G are midpoints of CB, BA and AC respectively.

AE, BF and CG are medians of the triangle.

We know that centroid divides the median in the ratio 2:1

Using this we find that AD:DE = 2:1

Or AD+DE:DE = (2+1):1

AE:DE =3:1

15:DE = 3:1 . Hence DE =5 cm.

On the similar grounds we find that DF = 1/3 BF = 9

Hence BD = DF-BF = 27-9 =18 cm

and also

CG = 3/2 times CD = 12 cm.

Which inequality is true?
DiKsa [7]

Answer:

C. 5\pi > 15

Step-by-step explanation:

In the given series of inequalities, the inequality sign determines the final outcome.

A. 4\pi - 2 < 10

4\pi < 12

\pi < 3

Since \pi < 3, then the inequality is false

B. \pi + 9 < 12

\pi < 3

Since \pi < 3, then the inequality is false

c. 5\pi > 15

\pi > 3

Since \pi > 3, then the inequality is true

D. 6 > 2\pi

3 > \pi

Since \pi < 3, then the inequality is false

Thus, the only inequality that is true is option C.
