Marine biologists want to estimate the green sea turtle population in Florida. They tag 400 green sea turtles. Over the next 4 months, they gather four samples of 75 green sea turtles each and record how many have a tag. The results are shown in the table. Based on these results, how many green sea turtles should they estimate live in Florida?

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
