Answer:
A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements.

Answer:
octagon, a regular polygon and convex
Step-by-step explanation:
The given shape has eight sides and all these shapes do not intersect each other, thus by the definition of polygons, the polygon which consists of eight sides is known as "octagon".
Also, A regular polygon is the polygon which has same sides and same angles and also the sides do not intersect each other.
Hence, the given shape is a regular polygon and also, the regular polygons are convex in nature.
Therefore, the given shape is octagon, a regular polygon and convex in nature.
Let us start by taking Trignometric Ratios
Let us take the ratio of Tan A (where A is some angle) between the hypotenuse formed by the distance between the top point of the pole and the outer most end of the shadow of the pole. So, the ratio will be
TanA=adjacent side/ opposite side
= 6/2 root 3 =3/root3
Rationalizing the ratio
3root 3/3 = root3
Hence the angle should be 60 as Tan A=Root3=Tan60
