Answer:
Step-by-step explanation:
4/1000=0.0004
200/10= 20
8/100=0.08
30/100=3
7/1000=0.0007
6/10=0.6
Y - y1 = m(x - x1)
Where y1 is the y-value of the point, x1 is the x-value and 'm' is the slope.
y - 8 = -1.2(x - 7)
Distribute -1.2 into the parenthesis:
y - 8 = -1.2x + 8.4
Add 8 to both sides:
y = -1.2x + 16.4
Answer: ∠DOB: 48°
Step-by-step explanation:
1. we need an equation first. the sum of all angles (108°, n°, 2n°) is equal to 180°. we can depict this with the equation: 108°+2n°+n°=180°
2. now we can solve for the missing variable, n.
108°+3n°=180° → subtract both sides by → 3n°=72° → divide both sides by 3 → n=24°
3. now that we know that n=24°, we can solve the value of ∠DOB. we can see that ∠DOB is 2n° which we just plug the number we got for n into the equation. 2*24=48° meaning ∠DOB is 48°
