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°.
1st you add up all the marbles so we got 15 so the answe will be out of 15 then next we add up nhe number of yellow and purple marbles 5+3= 8 so the answe will be 8/15
