Answer:
To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides.
Answer:
See explanation below:
Explanation:
Transit Photometry is the most widely-used and effective to date, it has been a method that measures the light curve of distant stars for periodic dips in brightness. These are the result of exoplanets passing or transiting in front of the star relative to the observer. It is currently the most effective and sensitive method for detecting extrasolar planets, particularly from an observatory in space. When combined with radial velocity data, a transit can also provide a good estimate of the planet's mass. This method detects distant planets by measuring the minute dimming of a star as an orbiting planet passes between it and the Earth.
The main reason direct detection of exoplanets is difficult is because most planets orbit planets orbit at small angular separations on the sky, this means a direct detection is only possible if the star's light can be suppressed or occulted such that the faint light from the planet can be detected.
Some planets are found via the wobble method, using both methods, combining mass and size, scientists can calculate the planet's density, an important step towards assessing its composition.

Explanation:
Human evolution and development is the process by which a human is beings developed on Earth from a now-extinct primates. Viewed from zoologically, we as humans are a Homo sapiens, a culture-bearing the upright-walking species that do lives on the ground and very likely have first evolved in Africa about 315,000 years ago. We are also now the only living members that what many zoologists are refer to as the human tribe, Hominini, but that there is abundant fossil as evidence to indicate that we were also preceded for millions of years by other hominins,
such as Ardipithecus, Australopithecus, and also other species of Homo, and that in our species also lived for a much time contemporaneously with at least one of other member of our present genus, H. neanderthalensis (the Neanderthals). In addition, to we and our predecessors have to always shared the Earth with other apelike primates, from the modern-day gorilla have the long-extinct Dryopithecus. That we can and the extinct of hominins are somehow related to and also that we and the apes, both living and also extinct, are also have somehow the related is accepted by the anthropologists and biologists in everywhere.
