Web1 dag geleden · When you check the arcsine of a value, you're working out the angle which produced that value when the sine function was operated on it. So: sin (30º) = 0.5 and sin -1 (0.5) = 30º When should the sine rule be used? The length of one side and the magnitude of the angle opposite is known.

Web1. The angles always add to 180°: A + B + C = 180°. When you know two angles you can find the third. 2. Law of Sines (the Sine Rule): a sin (A) = b sin (B) = c sin (C) When there is an angle opposite a side, this equation comes to the rescue. Note: angle A is opposite side a, B is opposite b, and C is opposite c.
