I'm pretty sure the answer would be 30 people.
Answer:
<h2>∠DBE = 105°</h2>
Step-by-step explanation:
Angles on one side of a straight line always add to 180°.
Therefore we have the equation:
![35+(3x-15)+x=180](https://tex.z-dn.net/?f=35%2B%283x-15%29%2Bx%3D180)
<em>combine like terms</em>
![(35-15)+(3x+x)=180](https://tex.z-dn.net/?f=%2835-15%29%2B%283x%2Bx%29%3D180)
<em>subtract 20 from both sides</em>
<em>divide both sides by 4</em>
![x=40](https://tex.z-dn.net/?f=x%3D40)
∠DBE = 3x - 15. Substitute:
![\angle DBE=\bigg(3(40)-15\bigg)^o=\bigg(120-15\bigg)^o=105^o](https://tex.z-dn.net/?f=%5Cangle%20DBE%3D%5Cbigg%283%2840%29-15%5Cbigg%29%5Eo%3D%5Cbigg%28120-15%5Cbigg%29%5Eo%3D105%5Eo)

The answer to this is 3x+8
The answer is A in my opinion
