Question

Please answer all 3 questions

Answer 1

Answer:

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

Step-by-step 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
