Sin theta of 30 degrees is1/2
Cos(120) = -0.5
Sin30 degrees is 0.50000
cosecant(x) = 1/sin(x)
My calculator tells me that sin 58 degrees = 0.84805
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.
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
all sin is sin97 degrees Fahrenheit = 36.1 degrees Celsius
The sine of 57 degrees is approximately 0.8387.
60 degrees
Sin is a ratio and so has no units.
No. If the angles are in the ratio 3:4:5, the sides will be in the ratio sin(3):sin(4):sin(5) - NOT in the ratio 3:4:5.
