You may print out this problem set using your browsers print feature, work on the problems at your leisure, and submit your answers later if you want (when printed the problems may include extra space for you to do your work). You may also save your work without it being graded using the Save button at the bottom of the page (this requires your password).

If you go back and correct the answers to the old problems and try to resubmit them, the grading software will catch you. You may attempt this problem set as many times as you want. You will receive whatever your best score louver all your attempts. In the following problems, solve for the indicated sides and angles of the triangles. A, B, and C denote the angles and a, b, and c the lengths of the opposite sides as indicated In the figure at the right. Your answers need to be correct to the nearest tenth. All angles are lobe given In degrees, using decimals, not minutes. For example, seventeen and a half degrees should be entered as 17.5. Warning: A fundamental principal for rounding numbers is that you only round reported final answers. Numbers used in Intermediate calculations should not be rounded. Every time you round numbers, you Introduce a small error. If you use these rounded numbers for further calculations, then the small errors will build up to become large errors (which will be marked wrong). So use the unrounded numbers for all calculations, then report the rounded numbers at the end. This is a requirement whenever you are doing careful calculations, whether In mathematics, the sciences, or engineering. Each answer box is worth 1 point.
