Hershey has stopped at a stoplight and noticed that his best friend, Marlene, is due west of him at the next stoplight, 30 feet away. Both are going to Hershey's Bakery. Hershey walks N 30* W to get there while Marlene goes N 72* E to get there. What is both of their distances to walk over to Hershey's Bakery?

After having a nice, long conversation with Hershey, they decided to see each other again the next day. They both leave the bakery at the same time. Marlene, in hurry to get to her cousin's Quinceanera, is headed at a bearing of 315* and is traveling 50 MPH. Hershey on the other hand goes home at 30 MPH at a bearing of 078*. How far apart are they after two hours?

WPP #12: Unit O Concept 10: Angles of elevation and depression

http://t0.gstatic.com/images?q=tbn:ANd9GcSKvHvNZVc5F7PgZG2008OF-l9bI4BbhjA7zstukLMqiBMq8DVS:www.firstfoo.com/wp-content/uploads/2013/09/wedding-cake-beautiful-light-blue-quinceanera-cake-with-princess-character-on-top-quinceanera-cakes.jpg

The Problem: 15anera: Sugar, oh Honey Honey.

Marlene's cousin is about to celebrate her traditional quinceanera. She put Marlene in charge of the cake design. Marlene has a friend that works in a pastry and she meets with him to ponder over the design. However, one major issue she has is that they need to figure out how tall the cake should be. For aesthetic reasons, Marlene wants the corner of the table (where the cake will be placed) 25 inches away from the the edge of the top cake. She wants the table edge of the table to be 30 inches from quinceanera doll's eyes at the top of the cake. She wants the angle of the doll's eyes to the corner of the table plus the angle of the corner of the table to the edge of the top cake to be around 60 degrees. If they decide to make the cake 4 feet tall and put a 4 inch tall doll on top, find the angle of depression and elevation to see if 4 feet is close to getting the ideal angle that Marlene is thinking of.
