Aconvex polyhedron has 6 vertices and 12 faces. how many edges does it have?me and i will give you the brainliest answer

16 edges.

Step-by-step explanation:

We will use Euler's polyhedron formula to solve for the edges of our convex polyhedron.

Euler's polyhedron formula is: , where,

V= Vertices of polyhedron,

F= Faces of polyhedron,

E= Edges of polyhedron.

Let us substitute V=6 and F=12 in Euler's formula to find number of edges of our polyhedron.

Let us subtract 18 from both sides of our equation.

Therefore, our convex polyhedron will have 16 edges.

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

a: inscribed angles
