Question

Use euler's formula to find

A) F=4 E=6 V=?
B) F=20 E=? V=12
C) F=? E=12 V=6

Answer 1

Answer:

A)4

B)30

C)8

Step-by-step explanation:

So the Euler's Formula is basically F+V-E = 2

A)F=4 E=6 V=?

F+V-E = 2

4+V-6 = 2

-2 + V = 2

       V = 2+2 =4

Here, V is 4

B) F=20 E=? V=12

  F+V-E = 2

20+12-E = 2

     32-E = 2

     32-2 = E

           E = 30

Here, E is 30

C) F=? E=12 V=6

F+V-E = 2

F+6-12= 2

   F -6 = 2

        F = 2+6

        F = 8

Here, F is 8
