Question

A polyhedron is given with 12 vertices and 28 edges. Find number of faces for this polyhedron.

Answer 1

Step-by-step explanation:

matching parts in triangle DEC and triangle BAC that you can find using the

given information are

O EC-CA, angle B - angle D, DE = AB

O EC=CA, CD - BC, DE = AB

O angle E-angle A angle ECD-angle ACB. angle B-angle D

O EC=CA, angle E-angle A, ED=AB
