Answer:

  • 120°

Step-by-step explanation:

<u>Diagonal BD of a given rhombus is angle bisector of ∠ADC, so:</u>

  • m∠ADB = m∠CDB

<u>Substitute the values and solve for x:</u>

  • 4x - 12 = 3x + 6
  • 4x - 3x = 6 + 12
  • x = 18

<u>Find the value of ∠ADC:</u>

  • m∠ADC = 2(4*18 - 12) = 120°
