Sin theta of 30 degrees is1/2
The value of sin 45 degrees, or sin(π/4 radians), is √2/2. This is derived from the properties of a 45-45-90 triangle, where the lengths of the legs are equal. Therefore, sin 45° represents the ratio of the opposite side to the hypotenuse in this triangle configuration.
Cos(120) = -0.5
The sine of 28 degrees, or sin(28°), represents the ratio of the length of the side opposite the angle to the length of the hypotenuse in a right triangle. Its approximate value is 0.4695, indicating that if the hypotenuse is 1 unit long, the opposite side would be about 0.4695 units long. Graphically, sin(28°) can be represented on the unit circle as the y-coordinate of the point corresponding to 28 degrees.
cosecant(x) = 1/sin(x)
Sin p is a ratio and so a number: it cannot have units such as degrees. As a result, the question is meaningless and so cannot be answered.
Suppose the base of the triangle is of length x cm and the equal sides are of length y cm.The base angles sum to 60 degrees so each is 30 degrees and the apex angle is 180-60 = 120 degrees.Then area = 132.61014 = 0.5*y2*sin(120)So that y2 = 132.61014/[0.5*sin(120)] = 306.25and therefore, y = 17.5 cm.Then, by the sine rule, x/sin(120) = y/sin(30)So x = y*sin(120)/sin(30) = 30.31 cmAnd therefore, perimeter = x + 2*y = 65.31 cm.

It is simply the sine of the supplementary angle. If x is an angle measuring (90, 180) degrees, then sin(x) = sin(180 - x).
If one of the other angles is x (degrees or radians in any units), then the ratio is sin(x) : cos(x).
120 degrees is the angle made by the hands of a clock at 4 o clock. To get this answer, you could divide the clock into equal parts (12), and find the ratio of the time in terms of parts to the total number of parts of the clock (which would be 4/12 in this case). Then, you cross multiply the ratio you got, to the ratio of the unknown degrees to the total number of degrees in a circle (x/360). (4 * 360 = 12x). The answer should be 120 degrees.
60 degrees
Use trigonometry and the sine ratio: sin = opp/hyp sin = 2/5 sin-1(2/5) = 23.57817848 or 23.6 degrees to 1 dp Angle with the horizontal = 23.6 degrees Angle with the vertical wall = 66.4 degrees
It is the Sine(Sin) ratio. Sin(angle) = o/h
all sin is sin97 degrees Fahrenheit = 36.1 degrees Celsius
The sine of 57 degrees is approximately 0.8387.
Sin is a ratio and so has no units.
