A polyhedron has 6 faces and 8 vertices. how many edges does it have?

12

Step-by-step explanation:

Euler's formula for polyhedra states

F + V - E = 2

where F is faces, V is vertices and E is edges

Here F = 6, V = 8, thus

6 + 8 - E = 2, that is

14 - E = 2 ( subtract 14 from both sides )

- E = - 12 ( multiply both sides by - 1 )

E = 12 ← number of edges

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
