Answer:

  • 39° 44' 52''

Step-by-step explanation:

Given

  • m∠DXB = 70° 15' 12''
  • m∠DXC = 30° 30' 20''

To find

  • m∠CXB

Solution

According to Angle Addition postulate:

  • m∠DXB = m∠DXC + m∠CXB

Therefore

  • m∠CXB = m∠DXB - m∠DXC
  • m∠CXB = 70° 15' 12''- 30° 30' 20'' = 39° 44' 52''
