Alfred Wegener found this out through the Continental Drift Theory.
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
Hey there
The correct answer is (D)
(D) = <span>people work in sweatshops because it is their best alternative

The organism which obtains energy directly from the producers only are herbivores.
Answer: herbivores
<u>Explanation:</u>
Herbivores are the animals which eat the plants. Plants are the producers of the food chain and the food web. Animals like elephant, deer have their teeth to grind plants and its parts.
Therefore, herbivores are the organisms which take up their energy from the producers only. Other listed options as decomposers feed on dead and decayed organisms and comes last in the food chain.
Omnivores are humans who eat plants as well as other animals for energy requirements.
