In the diagram shown, lines m and n are parallel and crossed by transversal line r. This creates an angle that measures 135º as
shown. If the measure of Z1 is given by the expression 4x – 3 then
solve for the value of x.

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
