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! ♡
Hello There!
As we h ave the first quiz score provided, we would need to find the score for the second quiz.
We will do this by dividing the questions answered correctly to the total number of questions on the quiz.
Let's begin.
27/30 = 90
Now, we know that she received a grade of 90 percent on the second quiz.
<u>Therefore, she performed better on the social studies quiz. </u>
The answer to this question would be: $1888.33/semi-month
To answer this question you need to convert the annual into semi-monthly. Annual mean every 1 year or every 12 months. Semi-monthly mean two times a month. Then the equation would be: $45,320 / year x (1 year/12month) x (1 month/2 semi-month) = $1888.33/semi-month
Answer:
the change is 8.4 degrees
Step-by-step explanation:
1.2x7=8.4
B has more because 10/5 is 2 and 8/12 is less
