Answer:

CD = 4

Step-by-step explanation:

I believe you know the geometric mean for altitudes?

CD = √AD * DB = √8 * 2 = √16 = 4

If you are not aware of this theorem, then use the similarity of triangles.

ADC ~ CDB

AD/DC = CD/DB (cross-multiply)

CD^2 = AD*DB,

CD = √AD * DB = √8 * 2 = √16 = 4

I heard this was the place to come for help! I guess I heard wrong This question has been out here for over an hour 4x-x/4+x+1/3

Don't be snarky !

4x - x/4 + x + 1/3 = 2x

Add up the 'x' terms on the left side: (4 + 1/4 + 1)x = 5-1/4 x = 21/4 x

Now the equation is: 21/4 x + 1/3 = 2x

2x is the same as 8/4 x . Subtract it from each side:

13/4x + 1/3 = 0

Subtract 1/3 from each side :

13/4 x = - 1/3

Multiply each side by 4 :

13 x = - 4/3

Divide each side by 13 :

x = (- 4/3) / (13) = - 4 / 39
