Answer:
triangle
Step-by-step explanation:
The cross section is a triangle.
Kx + c = 2
Subtract c from both sides:-
kx + c - c = 2 - c
kx = 2 - c
x = (2 - c) / k
In rectangular coordinates, the coordinates of (r, theta) are (r cos theta, r sin theta). Adding pi to theta reflects (sin theta, cos theta) across (0, 0). Multiplying r by -1 does so as well, so b will have no effect (as these effects cancel out). Adding a multiple of 2pi has no effect, so c has no effect either. The other two reflect (r, theta) across (0, 0), so they are not valid options. Thus, b and c are the answers.
