angles and parallel lines: find x, y given angles of quad,

[smart_pirate]

find x and y in each figure. what I am really having trouble with is setting the problem up
can anyone please help me set the problems up? please and thank you

here are the figures



and also find x,y and z in each figure, I am having the same problem

Assuming those horizontal lines are parallel-

what properties of parallel lines and and its transvaals you know ( like opposite interior angles are equal, etc.)

and also find x,y and z in each figure, I am having the same problem

For the first set of graphics: What is the angle sum of any quadrilateral? What is the angle sum of any triangle? This will at least allow you to solve for y in terms of x. (Lacking additional information, I see no way to find unique solutions, however.)

For the second set of graphs: Since we are given no information regarding parallelism, etc, I see no way to solve.

Please consult with your instructor regarding clarification. Thank you!
