chemistry set. Afterward, Arron and Brynn had the same amount of money left over.
Which equation can be used to find b, the cost of Brynn's chemistry set?

A: 77 - 60 = 36 - B
B: 77 + 60 = b + 36
C: 60 + 36 = b + 77
D: 60 - 36 = 77 - b

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
