If you know the sine, cosine, or tangent ratio for an angle, you can use the 2nd sin , 2nd cos , or 2nd tan keys on a calculator to determine the angle measure. Make sure that the calculator is in degree mode.
Tech Tip
The 2nd sin keys on a calculator may be labelled sin21 .
Hint
The sum of the measures of the angles in a triangle is always 1808.
