Hi CPhill!

I think cburns means the same side interior angles on two parallel lines cut by a transversal line:)

Hey cburns,

It would be a lot easier for the answers to help you out with your questions if you made them more specific so we know what you're asking for:)

Same side interior angles are supplementery, so they equal 180 when added together.

Therefore, if the top is 75 degrees, the bottom would be 180 - 75 

x = 105 degrees.

Or maybe cburns means trig in a right angled triangle.

Do you get the same answers whether you use θ or (90-θ) ?

Yes so long as you do the ratios properly you definitely get the same answer.

This is a real guessing game - is it not?

Actually reading it again, Kitty's interpretation is much more likely to be correct.

Co-interior angles on parallel lines are supplementary. (add to 180 degrees)
