Thread: Trouble With Triangles with Altitude

Okay. I'd doing this assignment and I came across a problem I absolutly know i got right but the computer says otherwise (possibly a programming error). Here it is:

In the diagram of ΔABC, m∠ACB = 90 and is an altitude. If AD = 2 and DB = 6, find AC.


1.)
2.) 4
3.) 6
4.) 4

It said it was 4.) 4, but I disagree.

Never mind. Read it wrong. Damn Castle Learning.
