HEY BUDDY HERE IS UR ANSWER
✨✨✨✨✨✨✨✨✨✨✨✨✨
Since EULER'S FORMULA = F+V=2+E
So,1)FACES=7
VERTICES=10
EDGES =x
F+V=2+E
7+10=2+E
17-2=E
E=15
2)FACES=y
VERTICES=12
EDGES =18
F+V=2+E
F+12=2+18
F=20-12
F=8
3)FACES=9
VERTICES=z
EDGES =16
F+V=2+E
9+V=2+16
V=18-9
V=9
SIMILARLY U CAN DO ALL AND
HAPPY NEW YEAR
