220.127.116.11 Apply the trigonometric ratios sine, cosine and tangent to solve problems, such as determining lengths and areas in right triangles and in figures that can be decomposed into right triangles. Know how to use calculators, tables or other technology to evaluate trigonometric ratios.
a) I can determine the correct trigonometric ratios in a
b) I can determine lengths and areas in right triangles,
and figures containing right triangles, using sine,
cosine, and tangent.
c) I can use calculators, tables or other technology to
find angle measures using inverse operations.
