Answer 1

Answer:

1

soln : Using euler's formula = F + V - E = 2

= F + 6 - 12 = 2

= F - 6 = 2

= F = 2 + 6

= F = 8

2

soln: Using Euler's formula = F + V - E = 2

= 5 +V -9 = 2

= V +5 -9 = 2

= V - 4 = 2

= V = 2 + 4

=V = 6

3

soln: Using Euler's formula = F + V - E = 2

= 20 + 12 - E = 2

= 32 - E = 2

= - E = 2 - 32

= - E = - 30

minus minus cancle

= E = 30
