The vertical shift, k, is the amount every
y-value is shifted when compared to the basic sine
or cosine function. In other words, it is the same y-
value as the midline. For the equation of this
graph,
k=

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
