-6a-48 that would be it because you are only distributing the -6
∠ADC = 112°
∠ADC =6x + 7 + 12x - 3
Equate both:
6x + 7 + 12x - 3 = 112
Solve for x :
6x + 7 + 12x - 3 = 112
Combine like terms:
18x + 4= 112
Take away 4 from both sides:
18x = 108
Divide both sides by 18:
x = 6
Find ∠ADB:
6x + 7 = 6(6) + 7 = 43
Answer: ∠ADB = 43°
Answer:
SSA (SIDE, ANGLE, SIDE)
Step-by-step explanation:
D. , this is a good way because this way you can easily multiply and then you'll see your answer right in front of you.
