Answer:
∠AOB and ∠COD are vertical angles
∠DOE and ∠COD are complementary, adjacent
∠AOB and ∠AOD are supplementary, adjacent.
Step-by-step explanation:
Let's start with ∠AOB and ∠COD.
Looking at this, we can see they are the same angles formed by two lines that intersected. These are vertical angles as they are opposite each other.
∠DOE and ∠COD together form the angle ∠EOC, which is a right angle. Complementary angles are any of two that add up to 90°, so these two angles are complementary. They are also adjacent because they are right next to each other.
∠AOB and ∠AOD together form the angle ∠BOD, which has a measure of 180°. Supplementary angles are any of two that add up to 180°, so ∠AOB and ∠AOD are supplementary. They are also adjacent as they are touching/right next to each other.

Step-by-step explanation:
if you take all of the numbers 5 5 6 6 7 7 7 8 8 8 9 9 9 9 10
8 is in the midle thus making it the median
i apologise if this is wrong i have not done this kind of math in a while, but i hope this helps
Answer:
(f+g)(x) = 3x^2 + 3/2x -9
Step-by-step explanation:
(f+g)(x) = f(x) +g(x) = (x/2 -3) + (3x^2 +x -6) . . . . add up the functions
= 3x^2 +x(1/2 +1) +(-3 -6) . . . . . combine like terms
= 3x^2 +3/2x -9
Answer:
14
Step-by-step explanation:
100% is 20
meaning that for every ten percent is two
so if you minus 30% 6 from 100% 20 you get 14
