Two parallel lines are crossed by a transversal. Parallel lines c and b are cut by transversal a. On line c where it intersects with line a, the uppercase left angle is 80 degrees. On line b where it intersects with line a, the bottom right angle is y degrees. What is the value of y? Y = 40 y = 80 y = 100 y = 120

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
