Given parameters:
Each interior angle = 150°
Unknown:
The number of sides of this regular polygon = ?
Solution:
To find the sum of internal angles of a regular polygon, we use the expression below;
(n - 2) x 180 = sum of internal angles of a polygon
n is the number of sides,
Also, the sum of the internal angles of a polygon = number of sides x internal angles;
So;
(n-2) x 180 = 150 x n
Solve for n;
180n - 360 = 150n
180n - 150n = 360
30n = 360
n = 12;
Therefore, the number of sides is 12

Answer:
x=-3
Explanation:
-8=-8(x+4) divide -8 into the other side
1= x+4 then subtract 4 on both sides
-3=x
<u>Answer:</u>
<em>C. Sulfur dioxide
</em>
<em></em>
<u>Explanation:</u>
Sulfur dioxide is a dangerous chemical, and it may create complications. An ingredient incorporated in the making of sulfuric acid because it is widely used in many industries. When starting a car in the morning, one interacts with Sulfur, and this is experienced when striking a match.
The substance is usually colorless and soluble in water forming a gas. Sulfur is not, however flammable, but it has a transition that happens during the volcanic and produces a waster product with materials that are heated.
