**What is Sexagesimal notation? Sexagesimal, also known as base 60 or sexagenary, is a numeral system with sixty as its base. It originated with the ancient Sumerians in the 3rd millennium BC, was passed down to the ancient Babylonians, and is still used—in a modified form—for measuring time, angles, and geographic coordinates.**

**Why do Babylonians use base 60?** “Supposedly, one group based their number system on 5 and the other on 12. When the two groups traded together, they evolved a system based on 60 so both could understand it.” That’s because five multiplied by 12 equals 60. The base 5 system likely originated from ancient peoples using the digits on one hand to count.

**What is sexagesimal Minutes second?** In the Sexagesimal system of measurement a right angle is divided into 90. equal parts called Degrees. Each degree is divided into 60 equal parts called Minutes, and each minute into 60 equal parts called Seconds. The symbols 1°, 1′, and 1″ are used to denote a Degree, a Minute, and a Second respectively.

**When did the Sexagesimal system start?** Developed around 3100 B.C., the sexagesimal system, as it is known, has fallen out of favor but is still used (with slight adjustments) to measure time and angles. Most modern societies use the base-10 system (also called decimal) of Hindu-Arabic numerals.

The Babylonian number system uses base 60 (sexagesimal) instead of 10. Their notation is not terribly hard to decipher, partly because they use a positional notation system, just like we do. To us, the digit 2 can mean 2, 20, 200, or 2/10, and so on, depending on where it appears in a number.

The first modern equivalent of numeral zero comes from a Hindu astronomer and mathematician Brahmagupta in 628. His symbol to depict the numeral was a dot underneath a number.

Muhammad ibn Musa al-Khwarizmi was a 9th-century Muslim mathematician and astronomer. He is known as the “father of algebra”, a word derived from the title of his book, Kitab al-Jabr. His pioneering work offered practical answers for land distribution, rules on inheritance and distributing salaries.

Answer: A) Degree is the largest unit in Sexagesimal system.

The Sumerian invention of cuneiform—a Latin term literally meaning “wedge-shaped”— dates to sometime around 3400 B.C. In its most sophisticated form, it consisted of several hundred characters that ancient scribes used to write words or syllables on wet clay tablets with a reed stylus.

Meet the world’s first emperor. King Sargon of Akkad—who legend says was destined to rule—established the world’s first empire more than 4,000 years ago in Mesopotamia.

Modern usage

One hour of time is divided into 60 minutes, and one minute is divided into 60 seconds. Thus, a measurement of time such as 3:23:17 (3 hours, 23 minutes, and 17 seconds) can be interpreted as a whole sexagesimal number (no sexagesimal point), meaning 3 × 602 + 23 × 601 + 17 × 600 seconds.

The geographic coordinates for the White House in Washington DC are: 38˚ 53′ 52” North (Latitude) and 77˚ 2′ 12” West (Longitude).

Computer scientists Vinton Cerf and Bob Kahn are credited with inventing the Internet communication protocols we use today and the system referred to as the Internet.

Credit for our modern version of the school system usually goes to Horace Mann. When he became Secretary of Education in Massachusetts in 1837, he set forth his vision for a system of professional teachers who would teach students an organized curriculum of basic content.

If we were to go by historical sources, then exams were invented by an American businessman and philanthropist known as Henry Fischel somewhere in the late 19th century. However, some sources attribute the invention of standardized assessments to another man by the same name, i.e. Henry Fischel.

Archimedes is known as the Father Of Mathematics. He lived between 287 BC – 212 BC. Syracuse, the Greek island of Sicily was his birthplace. Archimedes was serving the King Hiero II of Syracuse by solving mathematical problems and by developing interesting innovations for the king and his army.

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols. Just as sentences describe relationships between specific words, in algebra, equations describe relationships between variables.

Given $ {150^g} $ we have to convert it into degrees. Therefore, 150 grades in the centesimal system are equal to 135 degrees in the sexagesimal system. Note: Centesimal system is better to use than sexagesimal system in measuring angles. 1 degree is equal to 10/9 grades.

Centesimal System : when right angle is divided into 100 equal parts called grades then we use a Centesimal System system. 1 grade is divided into 100 equal parts called minutes and is denoted as 100′ . Again each minute is divided as 100 parts called seconds and is denoted as 100′′ .

There are two commonly used units of measurement for angles. The more familiar unit of measurement is that of degrees. A circle is divided into 360 equal degrees, so that a right angle is 90°.

An angle could have a measurement of 35.75 degrees. Notice that here we are expressing the measurement as a decimal number. Using decimal numbers like this one can express angles to any precision – to hundredths of a degree, to thousandths of a degree, and so on.

Yotta is the largest decimal unit prefix in the metric system, denoting a factor of 1024 (1000000000000000000000000), or one septillion.

Cuneiform is a logo-syllabic script that was used to write several languages of the Ancient Near East. The script was in active use from the early Bronze Age until the beginning of the Common Era. It is named for the characteristic wedge-shaped impressions (Latin: cuneus) which form its signs.

Genghis Khan

Khan was the founder of the Mongol Empire, the largest land-based empire the world has ever seen. Given the size of his army, the levels of discipline and training he instilled were incredible.

Mesopotamian religion was polytheistic, with followers worshipping several main gods and thousands of minor gods. The three main gods were Ea (Sumerian: Enki), the god of wisdom and magic, Anu (Sumerian: An), the sky god, and Enlil (Ellil), the god of earth, storms and agriculture and the controller of fates.
