Answer:

  • 30°

Step-by-step explanation:

The angle between two secants is half the difference of intercepted arcs.

  • m∠ACB = 1/2(mAB - mDE)

Substitute the arc values and calculate

  • m∠ACB =1/2(80° - 20°) = 1/2(60°) = 30°

Answer:

∠ACB = 30°

Step-by-step explanation:

Finding ∠ACB :

  • ∠ACB = 1/2 x (∡AB - ∡DE)
  • ∠ACB = 1/2 x (80° - 20°)
  • ∠ACB = 1/2 x 60°
  • ∠ACB = 30°
