Answer:
Step-by-step explanation:
<u>We need to add up 4 angles to get 360.</u>
<u>Here is what you fill out for the missing boxes:</u>
- 70 + 70 = 130
- 70 goes into the smallest angle.
- 115 + 115 = 230.
- If we do 120 or 130, It would make 370 or 390.
- 130 + 230 = 360.
- 50 + 50 = 100.
- Missing 50 goes into smallest angle.
- 130 + 130 = 260.
- 260 + 100 = 360.
Answer:
Step-by-step explanation:
Let
V
be the number of vertices of a polyhedron,
F
the number of faces of that polyhedron, and
E
be the number of edges. The quantity
χ
=
V
−
E
+
F
is called the Euler characteristic (of a polyhedron). In the case of convex polyhedra,
χ
=
2
.
Consider, for example, a tetrahedron (which is the simplest solid). It has 4 faces,
1
2
(
4
)
(
3
)
=
6
edges, and
1
3
(
4
)
(
3
)
=
4
vertices. Thus we have
V
−
E
+
F
=
4
−
6
+
4
=
2
.
Euler's formula holds for all Platonic solids (tetrahedron, cube, octahedron, dodecahedron, and icosahedron). Since a cube and an octahedron are dual polyhedra (each is formed by connecting the centers of the faces of the other), their
V
and
F
values are equal to the
F
an
V
values of the other. (The same is true for the dodecahedron and icosahedron).
Answer:
The Answer is: C. 10 x 10^7
Step-by-step explanation:
The others are in Scientific Notation. The decimal is just to the right of the number and then 10 with an exponent defines the actual size of the number.
Hope this helps! Have an Awesome Day!! :-)
