∠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:
1500 g
Step-by-step explanation:
To find the mass of each bag, we divide 6 kg by 4.
(6 kg)/4 = 1.5 kg
Now we convert 1.5 kg to g.
1 kg = 1000 g
1.5 kg * (1000 g)/(1 kg) = 1500 g
Answer:
1/4
Step-by-step explanation:
The dot product of two vectors is defined as the sum of the multiplication of each of its components.
We have then:
B = [2 8 .6 3]
A = [3 0 2 -1]
Making the product point:
BA = [2 8 .6 3] [3 0 2 -1]
BA = (2 * 3) + (8 * 0) + (0.6 * 2) + (3 * (- 1))
BA = 4.2
Answer
BA = 4.2
Answer:
-9
Step-by-step explanation:
2 - 3 + (-5) +(-3)
= 2 - 3 -5 -3
= 2 - 11
= -9
