DG^2 = 9^2+15^2

OpenStudy (anonymous):

DG^2- 10^2= CG^2

OpenStudy (anonymous):

I dont know DG

OpenStudy (anonymous):

17.5 or something

OpenStudy (jadedry):

Wow, apologies, I've made a terrible mistake. \[AG^2 - AD^2 = DG^2\]

OpenStudy (anonymous):

What is DG? Is it 17.5???

OpenStudy (jadedry):

DG = 12 15^2 - 9^2 = 144 \[\sqrt 144 = 12\]

OpenStudy (anonymous):

OHHHH whoops i added from the other equation u posted because u put + not -

OpenStudy (jadedry):

@angel12310 Yes, I made a mistake. ^^;

OpenStudy (jadedry):

So, now that you know DG = 12 CG = ?

OpenStudy (anonymous):

6.63= 6.6?

OpenStudy (jadedry):

Yes that is correct. c:

OpenStudy (anonymous):

SO i put 6.6

OpenStudy (jadedry):

Yes, to the 10th of an inch.

OpenStudy (anonymous):
