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)

Re: 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.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

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
