Brahmagupta’s mathematical discoveries and work came about while studying a branch of science. what was he studying?

1.psychology
2.economics
3.astronomy
4.geology

The answer should be "astronomy". Brahmagupta was born in northwestern India in 598 CE. Very little is known about his early life, but like most mathematicians of that time in India, his work was deeply rooted in astronomy. As a young adult, he developed a talent for using mathematics to solve cosmic problems. By the age of thirty, he was a court astronomer to the king.

Brahmagupta became the head of India’s first observatory, located in the city of Ujjain. There, he used numbers and patterns to investigate the planets and stars. He wrote all of his findings in two books on astronomy and mathematics, Brāhmasphuṭasiddhānta and Khandakhadyaka. Hope this helps. Thanks!

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
