walls of two buildings on either side of a street are parallel to each other. a ladder 5.8 long is placed on the street such that its top just reaches the window of the building at the height of 4m. on twining the ladder over to the other side of the street, it's top touches the window of the other building at a height 4.2m find the width of the street.​

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
