∠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:
24. because 2009-2005+20 = 24. hope that helps
1/4= 0.25%
25%>0.25
So, 25% of 80 is more than 1/4% of 80 and 1/4% of 80 is less than 25% of 80.
