Elena is trying to figure out how many movies she can download to
her hard drive. The hard drive is supposed to hold 500 gigabytes
of data, but 58 gigabytes are already taken up by other files. Each
movie is 8 gigabytes. Elena wrote the inequality 8x + 58 > 500 and
solved it to find the solution x > 55.25.

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
