The equation we'll use for this is:Total Gifts = Veronica's Gifts (v) + Natalie's Gifts (n).
12 = v + n
The problem says Veronica got 3 times as many gifts as Natalie.
You can directly translate this into an equation!
v = 3 * n = 3n. This means we can replace any v with 3n.
So, 12 = v + n = 3n + n = 4n
12 = 4n
3 = n. Natalie got 3 gifts.
We can now plug back in for Veronica's gifts:
v = 3n
v = 3(3)
v = 9. Veronica got 9 gifts.
Answer: F) 180°
Step-by-step explanation:
The sum of any two adjacent angles of a parallelogram is equal to 180°.
Cosine Law:
c² = a² + b² - 2 a b cos C
Answer:
C ) area of square c² = area of square a² + area of square b²
- area of defect 1 - area of defect 2
Answer:
Yes.
Step-by-step explanation:
Because yes.
Yes, I will list acute first (<90) and obtuse second (>90) and they need to add to 180
10 and 170

30 and 150
40 and 140
50 and 130
60 and 120
70 and 110
80 and 100 and so on
