I think the answer is trhat they are complmentary

- tkhunny

Complimentary angles sum to 90º.

- anonymous

18+72= 90 doesnt it?

- anonymous

But yet the dcb doesnt make a full angle

- tkhunny

DCF is 72
DCB is 72 + 54 + 36

- anonymous

it is 162

- anonymous

So what would it be!

- tkhunny

You tell me...
Ruled Out -- complementary angles
vertical angles
linear pair
Definitely Not -- right angles
Running out of choices.

- anonymous

Sorry but i cant find the answer that fits

- anonymous

So it is Ah vertical angles consist of what degree?

- tkhunny

Well, Vertical Angles are Congruent. Are these two angles congruent?

- anonymous

No

- anonymous

So its either linear and complimentary

- anonymous

Brain buster!

- tkhunny

Then we had better figure out what a "Linear Pair" is, since we already threw out complementary.

- anonymous

Is a linear pair

- tkhunny

Are the two angles supplementary (add to 180º)?

- anonymous

Is it klike some where 110 and 720 degrees

- anonymous

70*

- anonymous

Ok i am comfused

- tkhunny

Ys, you are. Just answer my question.

- anonymous

What does angle DCB equals to?

- tkhunny

Already defined above. No fair asking the same question twice.

- anonymous

Ok

- anonymous

Witch angles your talking about?

- anonymous

Are you talking about this
DCF is 72
DCB is 72 + 54 + 36

- anonymous

It equals 162

- anonymous

So do i add angle ACD witch equals 18

- anonymous

that amkes the equation to 180

- anonymous

That would be supplementary but i dont have it as a option

- tkhunny

Hold on. Please slow down. Think a little more and type a little less. Take a deep breath.
The question to answer is this: Are ACD and DCB Supplementary (add to 180º)?
Just answer the question. Don't try to jump ahead. Do NOT look at the answers.

- anonymous

Yes they are supplmentary

- tkhunny

Perfect. Next question. Are they also "Adjacent". This means they share one ray.

- anonymous

No they dont

- anonymous

They dont share the same ray

- anonymous

Wait they do?

- tkhunny

What is DC? Isn't that part of both ACD and DCB?

- anonymous

Yeah its the vertex

- anonymous

They are adjacent

- tkhunny

That's really enough to answer the question, but just to emphasize the definition, simply look at the two angles. Look particularly at the two rays they do NOT share. Does it appear that these two rays form a straight line?

- anonymous

But

- anonymous

I still dont get a corhesive asnwer

- anonymous

i GET THE DEFINITION

- anonymous

Caos*

- tkhunny

Why are you looking at the answers? Just answer the question.

- anonymous

But i dont know waht option it is

- anonymous

Because i need the answer to answer the question

- anonymous

They do form a straight line?

- anonymous

Well atleast i guess

- tkhunny

You need to understand the concept more than you need the answer. You need to slow down. You cannot process this information at the speed you want to.
Thank you.
Supplimentary
Adjacent
Line
Two angles with these properties are a "Linear Pair". That is the answer.
Think through it a piece at a time. Don't try to pounce on it!

- anonymous

Ok
