Answer:
x=13
y=25.666...
<DME=25°
<BMQ=25°
<EMQ=155°
Explanation:
3x-14=x+12
3x-x=12+14
2x=26
x=13
<DME=3x-14=3(13)-14=39-14=25
<BMQ=x+12=13+12=25
If DME and BMQ each equal 25, EMQ=180-25=155
6y+x-12=155 PLEASE CHECK - I think the picture says 6y+x-12, but if it doesn't, then this last part needs to be redone.
6y+13-12=155
6y+1=155
6y=155-1
6y=154
y=25.66666...
