Answer:
34 edges
Step-by-step explanation:
Euler's formula for polyhedron states
F + V - E = 2
where F is number of faces, V, number of vertices, E number of edges
Here F = 16, V = 20, thus
16 + 20 - E = 2, that is
36 - E = 2 ( subtract 36 from both sides )
- E = - 34 ( multiply both sides by - 1 )
E = 34
Answer:
x=21
Step-by-step explanation:
61+34 = 95
360( a circle) - 95 = 265
265 +7 +22 = 294
9x+5x=14x
294=14x (divide both by 14 to get x)
X=21
