Answer 6

i'm thinkin a would be the answer

Answer 7

Here are adjacent angles. Look at figure below, where angles 1 and 2 are adjacent.

Answer 8

Adjacent angles are just what the word "adjacent" means. They are next to each other. They must have a common side and one cannot be inside the other one.

Answer 9

Are angles DOA and BOC really adjacent angles?

Answer 10

no because they are congruent

Answer 11

i am here

Answer 12

note: this drawing is not to scale


Here we can see that all of the angles are formed from intersecting lines that meet with AOB. Also, we can see that these angles all add up to 180 degrees (since they are all supplementary)


So that means that the sum of all of the angles is 180

So it can be translated to....

5x%2B%283x%2B30%29%2B%282x%2B10%29=180



5x%2B3x%2B30%2B2x%2B10=180 Remove the parenthesis



10x%2B40=180 Combine like terms on the left side


10x=180-40Subtract 40 from both sides


10x=140 Combine like terms on the right side


x=%28140%29%2F%2810%29 Divide both sides by 10 to isolate x



x=14 Divide

Answer:
So our answer is x=14

Answer 13

You are correct that the aren't, but it's not because they are congruent. Those two angles are not next to each other. That's why they are not adjacent. A is not correct.

Answer 14

they must be vertical then right? and hi raven she's my fave

Answer 15

Correct. They are vertical.

Answer 16

Thanks you guys!

Answer 17

BTW, they are vertical because of their positions. It has nothing to do with angle AOB being a right angle.
