Answer:

  • CD = 5.2 cm
  • A = 27 cm²

Explanation:

As per diagram we have:

  • m∠A = 30°
  • m∠BCD = 30°

As per 30° right triangle property:

  • CD = √3×CB/2 = 3√3 ≈ 5.2 cm
  • and
  • AC = 2CD = 2×5.2 = 10.4 cm

Area of triangle:

  • A = 1/2bh
  • A = 1/2CB*AC
  • A = 1/2*5.2*10.4 ≈ 27 cm²
