non-parallel

how much do  non-parallel angles equal? like do the angles still equal 180?

Here is what the question says

If AB | CD:

6. What is the measure of angle 3 in degrees if angle 1 = 125?
A 26o
B 49o
C 32o
D 78o
E 42o
F 55o

(The one slash line means non-parallel)

Isn't there a picture that came with this question?

Re: non-parallel

Hi;

I think so.

Hi zee-f;

You can use the degree from the top of the page.


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?

Re: non-parallel

hi zee-f,

You will have to give us a diagram.  Without it, angle 1 and angle 3 could be anything.

I've made a guess below.

Re: non-parallel

Hey guys,

They didn't give me any diagram that is all what the question said,  that is why am confused. I got all the questions correct except for the questions about that all it said is if AB | CD which means if AB isn't parallel to CD then it asked questions neutral

Re: non-parallel

hey again I asked my teacher she said it was a typo. So it's  AB || CD. Now I know how to solve the problem.

Re: non-parallel

I got a full lesson complete 10/10 smile

here is what I answered for that question I was confused on:

6- F 55°
6. What is the measure of angle 3 in degrees if angle 1 = 125°?
A 26°
B 49°
C 32°
D 78°
E 42°
F 55°

7-B 168°
7. What is the measure of angle 8 in degrees if angle 7 = 12°?
A 15°
B 168°
C 98°
D 174°
E 101°
F 25°
