In an ABC triangle where 0 < A < 90, the sine of angle A is always less than 1 (since it is the ratio of the side opposite the angle A and the hypotenuse). The cosine of angle A is always greater than 0 (since it is the ratio of the adjacent side and the hypotenuse). Hence, the sum of sine of angle A and the cosine of angle A will always be less than 1, and cannot be greater than 1.
