Answer:

  • 4x - 3
  • 5x - 3

Step-by-step explanation:

  • m∠BEC = (2x+3)
  • when x = 30°
  • m∠BEC → (2(30)+3) → 63°

m∠AED = (360-2(63))/2

m∠AED = 117°

solve for first:

(4x - 3)

(4(30) - 3)

117° ............matches.

solve for third:

5x - 33

5(30) - 33

117° ........matches

Hence the first option and third is correct. rest two are wrong.
