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:
The correct answer is B. A watershed is the area contributing water to the runoff of a stream system.
Explanation:
A watershed or hydrographic basin is a territory drained by a single natural drainage system, that is, its waters give the sea through a single river or that it pours its waters to a single endorheic lake. A hydrographic basin is delimited by the line of the summits, also called water division. The use of natural resources is regulated administratively by separating the territory by river basins, and with a view to the future the river basins are emerging as one of the functional division units with much more coherence, allowing true social and territorial integration through water.

The fault is younger than the lower rocks but older those above it.
Explanation:
A fault found that cuts through lower rock layers but not those above it suggests that the fault is younger than the lower rock but older than those above it.
This interpretation is based on the principle of cross-cutting which states that "an intrusion or fault is younger than the rocks they cut through".
- In essence, an intrusion or fault cannot cut through a rock sequence unless it is already in place.
- This is why the fault that cuts through the rock layers is younger than the rock layers.
- But since it did not pass through the layers above, it is older than it.
