Cosine degree calculator
Notes on Find That Side or Angle Learning Task
Now, use your calculator to find the measure of the angle itself. Pressing “2nd” followed by one of the trigonometric function keys finds the degree measure corresponding to a given ratio. Press 2nd, SIN, followed by the sine of the angle from part a. What value do you get? Press 2nd, COS , followed by the cosine of the angle from part b.
