Given, Altitude AD = 12
So, Side = 2/(sqrt3) *12
Answer choice 1

is the altitude 12? the relationship given is AD/BC = 12.(altitude to side)
I still don't see the answer.

Yes the altitude is 12.nidhis.1408 wrote:is the altitude 12? the relationship given is AD/BC = 12.(altitude to side)
Question says....Altitude AD (which is perpendicular to Side BC)
We can say Altitude AD to side BC which means AD is perpendicular to BC.
Just select that black portion or keep your mouse pointer on that......I still don't see the answer.

I think it means that the altitude is from angle A to point D, which is on side BC. It's just poorly worded.nidhis.1408 wrote:is the altitude 12? the relationship given is AD/BC = 12.(altitude to side)
