Answer 1

Answer:

Prime factorization method of finding the square root of a number is the method in which the number whose square root is ...

Answer 2

Sin ( x + y ) = Sin ( 90 ) and Cos ( x - y) = Cos ( 30 )

bcoz. Sin ( 90 ) = 1. and Cos ( 30 ) = √3 / 2

=>. x + y = 90... equation 1

and

x - y = 30.... equation 2

Adding both the equations

x = 60 and. y = 30
