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)

Hi;

I think so.

Hi zee-f;

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

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.

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

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.

I got a full lesson complete 10/10

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°
