Has anyone see this happen?
I think their answer is wrong..
They have a triangle ABC, And a point D on AC. BDC = BCD = 2xdegree.
What is BC?
1) AD = 6
2) x = 36
They say AD = 6 is sufficient to know the length of BC.
I dont think so.. We know BD = BC, because angles are equal.. but I dont know how do they conclude AD = BD from this? Please help..
Has anyone else seen this?
Something is defenitely missing. There's no way we can conclude AD=BD..
