The measure of ADB is 61°

From the diagram ;

  • ∠ABC = 115°

∠ADC = ∠ABC (opposite angles are congruent)

115 = (4x + 6) + 6x - 11

115 = 10x - 5

115 + 5 = 10x

120 = 10x

x = 12

ADB = 6x - 11

ADB = 6(12) - 11

ADB = 61°

Hence, the measure of ADB is 61°

Complete Question:

m∠ABC = 115 ; Find ∠ADB
