So sorry! That was a long assignment!
I am thinking that several of you might be having some difficulty recognizing the SSA case with two solutions.
Keep in mind that you can find the height of a triangle if you know the angle opposite the height and the hypotenuse of that right triangle (SINE is OPPOSITE/HYPOTENUSE; height/b). If h is less than the "swinging side" a and a is less than b (the side adjacent to A), then there are two different triangles that can be drawn. One is obtuse, one is acute.
The quiz next block is very much like the worksheet attached below. I gave out the answers in class on Thursday, so I am not going to attach them below, just a new copy of the worksheet.
The extra help will be printed on the quiz.
There may be a problem with "minutes" of degrees. If so, you only need to know that 30' = .5 degrees and 15' = .25 degrees.
Quiz over 6.1 next block with a new assignment and notes over Law of Cosines.
Today we had a brief introduction to Law of Cosines. We went over homework in detail with work shown. We worked on the new HW #5 - Worksheet 6.1. A grade was taken over the textbook work on 6.1 (HW #4 - for 4 pts).
