Answer:

  • x = 30°
  • DB = 26
  • AD = BC = AB = DC = 7

Explanation:

  • Diagonals of a square are congruent and perpendicular and bisect each other

Q4

m∠AEB = 3x

m∠AEB = 90°

  • 3x = 90° ⇒ x = 30°

Q5

AE = 3x - 2

EC = 2x + 3

  • AE = EC
  • 3x - 2 = 2x + 3
  • 3x - 2x = 3 + 2
  • x = 5

DB = EC = 2(AE) = 2(3*5 - 2) = 2(13) = 26

Q6

AD and BC are the sides, which are equal

  • 2x - 1 = 5x - 13
  • 5x - 2x = 13 - 1
  • 3x = 12
  • x = 4

AD = BC = AB = DC = 2*4 - 1 = 7
