60, 60 and 60 degrees
There are two criteria: the angles have to all be equal and they have to add up to 180 degrees. This answer satisfies both criteria.
From the diagram you can see that plane cuts each lateral face of hexagonal pyramid and do not cut the base. A hexagonal pyramid has six lateral faces. The intersection of each of these lateral faces with given cutting plane is segment. The figure which consists of these segments is hexagon. This hexagon is not the same as base and even is not similar to the base because the cutting plane is not parallel to the base.
Answer: resulting cross section is a hexagon, correct choice is option 4.
The formula of the midpoint of HE:
We have H(0; 0) and E(2a; 2a). Substitute:
Answer:
c
Step-by-step explanation:
From the graph as x gets larger and becomes positive f(x) approaches 0 so the answer is C.
