Here's your strong hint: Tangents to a circle from an outside point are congruent.

Directrix (directrix):

Look at the marked up diagram that I attached above.

OpenStudy (anonymous):

oh, so 6 + 4.. 10?

Directrix (directrix):

If AB = 4, the AH = ? Tangents to a circle from an outside point are congruent.

OpenStudy (anonymous):

AH =4

OpenStudy (anonymous):

and.. HG =6

OpenStudy (anonymous):

So.. AH+HG = AH 4 + 6 = 10

OpenStudy (anonymous):

right? :)

Directrix (directrix):

Yes, let me get a sum and check with yours.

Directrix (directrix):

Did you do all the sides? AH = 10 By similar reasoning, get GE, EC, and AC.

OpenStudy (anonymous):

yes :D

Directrix (directrix):

Oh, we just had to find x?

OpenStudy (anonymous):

GE= 9 EC= 11 AC= 12

OpenStudy (anonymous):

Yes, just the x :)

Directrix (directrix):

x = AG so it is 10 as you said. GE= 9 EC= 11 AC= 12 -> These are also correct. Very good.

OpenStudy (anonymous):

yayyy :3 thank youuu x)

Directrix (directrix):

Alrighty.
