How could they not be?

Additionaly, that would mean that ACD is 25, how can this be???

**Yes, ACD is equal to BDC which is 25. They are mirror-images.**

Base angles of an isosc trapezoid are supposed to be congruent the one base angle BCD would be 60 and if DBC is 95 that would mean ADC is 120 which is not equal to 60.

**The base angles are.... BCD=ADC and DAB=CBA**

For BCD to equal ADC, ACD needs to be 85 not 25.

**No, ADC=25+35=60 degrees=BCD**

So why is this happening?
