Answer:

  • See below

Step-by-step explanation:

#1

  • m∠CDF = m∠5 + m∠1 = 42° + 117° = 159°

#2

  • m∠FDE = m∠FDG - m∠3 = 90° - 73° = 17°

#3

m∠ABC = m∠ABF + ∠mFBC

  • 159 = 7x + 20 + 2x - 5
  • 159 = 9x + 15
  • 9x = 159 - 15
  • 9x = 144
  • x = 144/9
  • x = 16

#4

m∠EBC = m∠DBC - m∠DBE

  • 3x + 13 = 12x - 3 - 5x - 12
  • 3x + 13 = 7x - 15
  • 7x - 3x = 13 + 15
  • 4x = 28
  • x = 7

m∠EBC = 3*7 + 13 = 21 + 13 = 34°

#5

m∠FBE = m∠FBC + m∠CBE and m∠FBC = m∠CBE

m∠FBE = 2m∠CBE

  • 10x - 9 = 4x + 15
  • 10x - 4x = 15 + 9
  • 6x = 24
  • x = 4

m∠FBE = 2*(4*4 + 15) = 2*31 = 62°
