Question

the number of faces and verticles of a polygon are 20 and 12 respectively . the number of edges are
​

Answer 1

Answer:

answer is 30

because

by the formula

F+V=E+2

F=faces

V=vertices

E=edge

so 20+12=E+2

32=E+2

E=32-2

E=30

Answer 2

Step-by-step explanation:

Euler's Formula for any polyhedron is, F+V−E=2

Where, F= Faces and V = Vertices and E = Edges

Therefore, it is given that F+V=32

So,32-E=2

So,-E=2-32

-E=-30

E=30.
