sin(360+30) =sin(30)= 1/2
Sin(X) = 0.9 X = Sin^(-1) 0.9 X = 64.158... degrees.

Sin(285) is a number, not an angle. The reference angle for 285 degrees is 285-360 = -75 degrees.
cos(35)sin(55)+sin(35)cos(55) If we rewrite this switching the first and second terms we get: sin(35)cos(55)+cos(35)sin(55) which is a more common form of the sin sum and difference formulas. Thus this is equal to sin(90) and sin(90)=1
To find a positive angle less than 360 degrees that is coterminal with 390 degrees, subtract 360 degrees from 390 degrees. This gives you 390 - 360 = 30 degrees. Therefore, the positive angle that is coterminal with 390 degrees and less than 360 degrees is 30 degrees.
There is no special name. An angle of 390 degrees, for example, is effectively the same as 390-360 = 30 degrees.

Sin(X) = 0.9 X = Sin^(-1) 0.9 X = 64.158... degrees.
Sin theta of 30 degrees is1/2
103.539 degrees Celsius = 102.2 degrees Fahrenheit.
The sine of 120 degrees can be found using the unit circle. It is equivalent to sin(180° - 60°), which gives sin(120°) = sin(60°). Since sin(60°) is √3/2, the ratio for sin 120 degrees is √3/2.
sin(90) = 1
