Questions & Step-by-Step Solutions

If cos C = 0.5, what is the value of angle C in degrees?
  • Step 1: Understand that cos C = 0.5 means we are looking for an angle C where the cosine value is 0.5.
  • Step 2: Recall that the cosine of an angle in a right triangle is the ratio of the adjacent side to the hypotenuse.
  • Step 3: Remember the special angles in trigonometry. One of the angles where cos C = 0.5 is 60 degrees.
  • Step 4: Therefore, angle C is 60 degrees.
