WebThe angle of incidence in the water is approximately 39°. At this angle, the light refracts out of the water into the surrounding air bending away from the normal. The angle of refraction in the air is approximately 57°. These values for the angle of incidence and refraction are consistent with Snell's Law.
Weba sin (A) = c sin (C) a sin (76°) = 9 sin (70°) a = sin (76°) × 9 sin (70°) a = 9.29 to 2 decimal places Similarly we can find side b by using the Law of Sines: b sin (B) = c sin (C) b sin (34°) = 9 sin (70°) b = sin (34°) × 9 sin (70°) b = 5.36 to 2 decimal places Now we have completely solved the triangle: we have found all angles and sides. WebSep 19, 2024 · The law of sine or the sine law states that the ratio of the side length of a triangle to the sine of the opposite angle, which is the same for all three sides. ... One of the most basic things you can do with trigonometry in a physics course is find the various side lengths and angle measurements for a right triangle.
