Use Euler's formula to find the missing number vertices: 16 edges: 43 face:???

mrs_skeptik [129]

Answer:

The number of faces is 29

Step-by-step explanation:

we know that

The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two

$V- E + F = 2$

In this problem we have

$V=16$

$E=43$

Substitute in the formula and solve for F

$16- 43 + F = 2$

$-27 + F = 2$

$F = 2+27$

$F = 29$
