Answer:
I think 140
Step-by-step explanation:
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:
Step-by-step explanation:
6 - 3(x + 1) = 18 ⇔ 3 - 3x = 18 ⇒ <em>x = 5</em>
y - 6 = 17 ⇒ <em>y = 23</em>
z - 3 = 4z ⇒ <em>z = - 1</em>
18 - 3(0) = 9w ⇒ <em>w = 2</em>
========================
I'm going to solve for you some another question you asked, I did not see the right answer... :)
There are two scenarios, because the expression under the module can be positive and can be negative: | 3x + 2| - 2 > 3 ⇔ | 3x + 2| > 5
<em>(1).</em> If <u><em>(3x + 2) is positive</em></u> then
3x + 2 > 5 ⇒ <em>x > 3</em>
<em>(2).</em> If <u><em>(3x + 2) is negative</em></u> then
- (3x + 2) > 5
- 3x - 2 > 5
- 3x > 7 ⇒ x < -
The final answer is <em>x < - 2.3 or x > 1</em>
You might have to check on this but i think you multiply all those numbers and divide by 2
The answer is 8 let get it !!
