Question

Pls answer this fast and properly ​

Answer 1

Answer:

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

a) Faces = 10

Edges =24

Let the vertices be x

using Euler's formula F+V-E = 2

→ 10+x-24=2

→ 10-24 +x =2

→ -14+x = 2

→ -14-2=-x

→ -16 = -x

(we will cancel minus by minus

and x=16)

→ So, No of vertices = 16

b) let the number of Faces be x

Edges = 15

Vertices = 10

using Euler's formula F+V-E = 2

→ x+10-15 =2

→x -5=2

→x=2+5

→x =7

So, No of faces = 7
