The sine of 75 degrees is about 0.9659
sine 40° = 0.642788
To find which angle has a sine of 0.13, you calculate arcsin or sin^-1(0.13) =7.47 degrees 7.47 degrees has a sine of 0.13. There is also another angle , below 360 , has a sine of 0.13. Subtract 7.47 from 180. 180-7.47 = 172.53 degrees also has a sine of 0.13.
Sin30 degrees is 0.50000
My calculator tells me that sin 58 degrees = 0.84805

It's not. The sine of 32 degrees is approximately 0.53. The sine of 59 degrees is approximately 0.86. For a definition of sine, see: http://en.wikipedia.org/wiki/Trigonometric_function .
There is probably a trick that I don't know (can't think of at the moment), but you can use the sine rule and sine ratio: The third angle is 180° - (62° + 48°) = 70° and is opposite the side of length 1.8cm. The side opposite the 48° can be found using the sine rule: a/sin A = b/sin B → a = b × sin A/sin B = 1.8 cm × sin48° / sin 70° The height can now be found using the sine ratio on the 62° angle as the side just found is the hypotenuse of that triangle: sine = opp/hyp → opp = hyp × sine → height = (1.8 cm × sin48° / sin 70°) × sin 62° → height = 1.8 × sin 48° × sin 62° / sin 70° cm ≈ 1.3 cm
sine-1(0.3420201433) = 20 degrees
The sine of 22.5 degrees is 0.383
sin77 = 0.974 Therefore the sine of 77 degrees is 0.974
The sine of 52.5 degrees equals 0.79335334029124. Hope I helped!
sine 40° = 0.642788
sine(15 degrees) = 0.25882 (rounded)
Sine of 225 degrees = - 0.5 sqrt(2)
No. The sine of an acute angle is less than 1. An acute angle is less than 90 degrees. The sine of 0 degrees is 0, and the sine of 90 degrees is +1. So the sines of the angles between 0 degrees and 90 degrees are less than 1.
Sine 3.3 degrees is about 0.057564. Sine 3.3 radians is about -0.157746. Sine 3.3 grads is about 0.051813.
