Question

please answer me my questions and correct don't fake answer I will report you okay ​

Answer 1

Euler's formula says,

F+V−E=2

i) F=7

V=10

E=15

So, F+V−E=2

ii) F=9

V=9

E=16

So, F+V−E=2

Answer 2

Euler's formula says,

F+V−E=2

a) F=7

V=10

E=15

So, F+V−E=2

b) F=9

V=9

E=16

So, F+V−E=2

Hence, verified.
