• cos (40) = 15 / BC
  &
  sin (50) = 15 / BC
• cos (50) = 15 / BC
  &
  sin (40) = 15 / BC
• cos (40) = BC / 15
  &
  sin (50) = BC / 15
• cos (50) = BC / 15
  &
  sin (40) = BC / 15

Given cos (40) = 15 / BC & sin (50) = 15 / BC

• sin (40) = BD / 19.6

  &

  tan (40) = BD / 15

• cos (50) = BD / 19.6

  &

  tan (50) = 15 / BD 

• sin (40) = BD / 19.6
  &
  BD = √(19.6² - 15²)
• cos (40) = BD / 19.6
  &
  BD = √(19.6² + 15²) 

Given sin (40) = BD / 19.6 or cos (50) = BD / 19.6

or tan (40) = BD / 15 or tan (50) = 15 / BD

or BD = √(19.6² - 15²)
