Answer:

75°

Step-by-step explanation:

Given

ADC=134°

So the equation is

5x+4+7x-2=134

12x+2=134

12x=134-2

12x=132

x=11

So BDC=

7.11-2

77-2

75

Answer:

m∠BDC = 75°

Step-by-step explanation:

m∠ADC =134°

m∠ADB+m∠BDC = m∠ADC

5x +4 +7x -2 = 134

12x = 134 -2

x= 132/12 = 11

m∠BDC = 7x -2 = 7*11 -2 = 77-2 = 75°
