Sin x = cos 53∘ What is the value of x?

Try this solution:

according to the rule sin (90-y) = cos (y), it is possible to re-write the given equation:

sin (90-y) = cos53°, where 90-y=x.

Then substituting the value y=53° into the equation 90-y=x, it is possible to find the 'x': 90-53=37°.

answer: 37°
