Question

What is the length of line AB?

Answer 1

That's a trick question.
Every line has infinite length.
Perhaps you mean the length of segment AB?

Answer 2

Yes that is what i ment

Answer 3

Is there enough information given to solve it?

Answer 4

We can get these angles using the inverse tangent function.

Answer 5

I don't think there is enough info on triangle ABP to answer unless we know that segment AB is parallel to segment L1L2.

Answer 6

If segment AB and segment L1L2 are parallel, then you can find the length of segment AB.

Answer 7

Ah yes forgot to mention that they are parallel

Answer 8

Then we can use more angles. See below.

Answer 9

Use the law off sines.
