Geometry - 1st, 2nd & 3rd blocks

Your "Finding Angles" classwork paper will be collected for a grade tomorrow.  Put an arc in the reference angle, label your sides (H, A, O) and then show the trig formula to solve each problem.   The answers are below.  Homework is to complete #9 - #14 on the "Using Trig Ratios to Find the Missing Side or Angle of a Right Triangle" worksheet.  If you complete ALL of the problems on that sheet, it will be extra credit to replace a 0 (or less than 100) homework grade.
