I'm confused. Can someone help me?

BOC is 80 COD is

60 (i think I’m not sure)

Step-by-step explanation:

DOF is 120 minus 40 (cuz it’s a vertical angle and is parallel from the other one) is 80 and I got 60 for COD because 80+80+40+40=240 a circle is 360 so 360-240=120 and since it’s two vertical angles you have to divide it by 2 to get 60. Again thts only what I think so Idk if it’s right or not this is what I think the answer is.

answer: no idea

step-by-step explanation: i just want points

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
