I agree that bcd is 94°
similarly, angle acd is x, so x+y+66=180.
Still looking for another angle (as it were) to connect x and y.
trapezium ABCD, with AB and DC being parallel, with diagonal connecting A and C, angle ABC is 86, angle ADC is y, angle dac is 66 and angle bac is x,
no angle given for bcd or bca or acd.
find x and y,
So I said that BCD is 94 deg, but then I get stuck
I think I'm probably missing some rule or something but not sure what it is.

I think it might be an error in the question, but thanks for trying at least I know it's not just me.
