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°

Answer:
a = -1.58
Step-by-step explanation:
1/3 +a+5/4 =0
1/3+5/4= -a
4+15/12 = -a
19/12 = -a
1.58= -a
1.58/-1 = -a/-1
-1.58 = a

Answer:
x = -1/10 or -0.1
Step-by-step explanation:
-1.8 - 6x = 6(0.1 + 3x)
-1.8 - 6x = 0.6 + 18x
-6x - 18x = 0.6 + 1.8
-24x = 2.4
-x = 2.4/24
-x = 24/10 / 24
-x = 24/10 * 1/24
-x = 24/240
-x = 1/10
x = -0.1
