This task has not been easy.
Answer:


Step-by-step explanation:





<span>When a plane intersects both nappes of a double-napped cone but does not go through the vertex of the cone, the conic section that is formed by the intersection is a curve known as hyperbola.
The standard form of the equation of the hyperbola is shown below:
[(x-h)^2/a^2]-[(y-k)^2/b^2]=1 (Horizontal axis)
</span>[(y-k)^2/a^2]-[(x-h)^2/b^2]=1 (Vertical axis)<span>
Therefore, the answer is: Hyperbola.

Answer:
It should be 60 degrees
correct me if wrong but since it's supplementary, you subtract 155 - 35 then from 180 and you get 60
Im not 100% about this tho but like 75% sure
