Use the image below to answer the following question. find the value of sin x° and cos y°. what relationship do the ratios of sin x° and cos y° share? a right triangle is shown with one leg measuring 12 and another leg measuring 5. the angle across from the leg measuring 5 is marked x degrees and the angle across from the leg measuring 12 is marked y degrees.

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
