Question

The value of sinA and cos A is less than 1. Why?

Answer 1

Step-by-step explanation:

Consider one of the non-90° angle in a right angle triangle (angle A). sinA is defined as the ratio of the side opposite to angle A and the hypotenuse. cosA is the ratio between the other non-hypotenuse side and the hypotenuse. In any right angle triangle, the longest side is called the hypotenuse, and the angle opposite to this side is the 90° angle. So, since the hypotenuse is the longest side, both ratios would have numerator lesser than denominaor, making them less than 1.
