Webcossine 3 years ago There can be two since sin (theta) = sin (180-theta) for all values of theta that are real numbers e.g. -1000.98, sqrt (2) etc. Since you are using the sin^-1 function you will only ever get 1 angle as the range is defined from -90 to 90 degrees (which is -pi/2 to pi/2 in radians). Websin A = (side opposite to A) / (long side) cos A = (side adjacent to A) / (long side) Because the side opposite to A is the one adjacent to (90°– A), it follows that the sine of one angle is the cosine of the other, and vice versa: sin A = a …
