Question

Find this thorough Euler's formula


please its so urgent..​

Answer 1

Answer:

Step-by-step explanation:

Euler's formula states that F+V-E=2

i) 6+8-12= 2

  14-12= 2

  2 = 2

ii) 5+x-8 = 2

   5+x = 2+8

   x = 10-5 = 5

Therfore, Vertices = 5

iii) 8+12-x = 2

   20-x = 2

    x = 20-2 = 18

Therfore, Edges = 18
