Which statement cannot be true? Explain.
A. \(\displaystyle{\sin{{A}}}={0.5}\)
B. \(\displaystyle{\sin{{A}}}={1.2654}\)
C. \(\displaystyle{\sin{{A}}}={0.9962}\)
D. \(\sin A = \frac{3}{4}\)

The sine of an angle can only be from -1 to 1. Since \(1.2654>1\), then choice \(B \sin A = 1.2654\) cannot be true.
