Question

if sin x = cos y , find the value of x+y

Answer 1

sin x = cos y
sin x = sin(90 - y)
CANCELLING SIN ON BOTH SIDES
So, x = 90 - y

AND FINNALY X + Y = 90

PLEASE MARK ME BRAINLIEST

Answer 2

sin x=cos y
$\sin(x) = \sin( \frac{\pi}{2} - y )$
$x = \frac{\pi}{2} - y$
$x + y = \frac{\pi}{2}$
