Answer:
sin37° - cos 53°=0
Step-by-step explanation:
sin37° - cos 53°
= sin 37° - cos(90°-37°)
= sin 37° - sin37°
/* Since , cos(90-A) = sinA */
= 0
Therefore,
sin37° - cos 53°=0

Answer:
we know that
sin (90-theta) = cos theta
also
cos(90-theta) = sin theta
(((((( where theta is the angle))))))
so
sin 37 = cos (90- 37) = cos 53
cos 53 - cos 53
= 0
Hope it helps ..............
