Answer:
7.2
Step-by-step explanation:
36 divided by 5 = 7.2
7.2 times 5 = 36.
Add the two angles and set them equal to 180, them solve for x
Answer:
Step-by-step explanation:
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
