Question

if sin(x+y)=1 and cos(x-y)=√3/2. find x and y

Answer 1

Answer:

Step-by-step explanation:

Hi Mate!!

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
