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
The cosecant of an angle is the reciprocal of the sine of that angle. So, to find the cosecant of 105 degrees, you first need to find the sine of 105 degrees. The sine of 105 degrees is approximately 0.9659. Therefore, the cosecant of 105 degrees is approximately 1.0353 (1 divided by 0.9659).
so 48 is the hypotnuese and 6 is the opposite so that will make sine sine(48 then divide 6 into whatever answer you got for sine(48 and you will see your answer
It is approx 0.2170
The sine of 75 degrees is about 0.9659
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 .
sine-1(0.3420201433) = 20 degrees
The sine of 22.5 degrees is 0.383
Let the angles be A B C and their opposite sides be a b c and so:- Angle A = 48 degrees Using the sine rule angle B = 58.7 degrees Angle C: 180-468-58.7 = 73.7 degrees Using the sine rule side c = 19.7 cm Alternatively: 180-58,7 = 121.3 which then is angle B and so:- Angle A = 48 degrees Angle B = 121.3 degrees Angle C: 180-48-121.3 = 10.7 degrees Using the sine rule side c is now 3.8 cm
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)
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
