What would be formed by a cross-section parallel to the base of a octagonal pyramid? A. octagon
B. circle
C. trapezoid
D. triangle

[A] Octagon

Step-by-step explanation:

"We are given a octagonal pyramid, So if we see it's base cross-section that form octagon as it has 8 sides."

A. octagon would be formed by a cross-section parallel to the base of a octagonal pyramid.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees
