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°
hope this heped! ♡
Answer:
8/12
Step-by-step explanation:
First
12 divided by 3 = 4
Second
since 12/3=4 you multiply 3x4 to get 12 so what you do to the denominator you do to the numerator so 2x4=8
Last
so that would give you
2/3 = 8/12
Answer:
bouton
Step-by-step explanation:
If you are adding all the angles, then it equals 180 degrees.
If you are looking for the missing angle out of 360.. then it is 180
Answer: your right answer is option 2
