Let the measure of angle Y be ( y ) degrees. Then, according to the given information, the measure of angle X is ( 2y - 30 ) degrees. Since the sum of the measures of angles X and Y is 90 degrees, we have the equation ( (2y - 30) + y = 90 ). Solving this equation will give us the measure of angle X.
