Hey user!
your answer is here..
we know about EULER'S FORMULA, it is a formula used to verify a polyhedron or to calculate the number of faces, vertices or edges.
Euler's formula = F + V - E = 2
given :-
faces = 28, verticies = 50 and edge = ?
we know that F + V - E = 2
therefore 28 + 40 - E = 2
==> 68 - E = 2
==> - E = 2 - 68
==> - E = - 66
==> E = 66
hence, the number of edges of the polyhedron is 66.
cheers!!
Answer:
parallelogram, quadralateral, and rhombus
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The surface area (A) of a sphere is calculated as
A = 4πr² ← r is the radius
here r = 2, hence
A = 4π × 2² = 4π × 4 = 16π units² → A
Answer:Side lengths: 2cm, 3cm, 4cm ... or you. F5. Angle measures: 30, 60, 90. SE. Isosceles. D6. Angle measures: 20: ... Use the diagram of the ... LJVK and Z KVL are called adjacent angles because they have a common vertex and a common side.
