First, drag a value to represent the missing angle in the triangle. Then, complete the trigonometry equality statements.

• missing angle = 90 - theta
  sin 28 = cos 62
  cos 33 = sin 57
  cos 31 = sin 59
  cosine 90 - theta = sin(theta)

• missing angle = 90 - theta
  sin 28 = cos 57
  cos 33 = sin 62
  cos 31 = sin 59
  cosine 90 - theta = sin(theta)

• missing angle = sin theta
  sin 28 = cos 62
  cos 33 = sin 57
  cos 31 = sin 59
  cosine 90 - theta = 90- theta

• missing angle = 90 - theta
  sin 28 = cos 59
  cos 33 = sin 57
  cos 31 = sin 62
  cosine 90 - theta = sin(theta)
