What is the sin theta of 30 degrees?
Sin theta of 30 degrees is1/2
What is the cosine of 120 degrees?
Cos(120) = -0.5
What is the value of sin 30 degrees?
Sin30 degrees is 0.50000
What is a cosecant ratio?
cosecant(x) = 1/sin(x)
What is the sine of 58 degrees?
My calculator tells me that sin 58 degrees = 0.84805
Given that sin p equals 50 degrees express tan -130 degrees in terms of p?
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.
What is the perimeter of an isosceles triangle whose base angles add up to 60 degrees and has an area of 132.61014 square cm showing work?
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.
Every angle theta between 0 and 360 degrees for which the ratio of sin theta to cos theta is -3?
108.435 degrees 288.435 degrees (decimal is rounded)
What is the sine ratio of obtuse angles?
It is simply the sine of the supplementary angle. If x is an angle measuring (90, 180) degrees, then sin(x) = sin(180 - x).
What the ratio of lenths of two sides of a right triangle?
If one of the other angles is x (degrees or radians in any units), then the ratio is sin(x) : cos(x).
What is sin 57 degrees?
sin 57 degrees
What angle is made by the hands of the clock at four o'clock?
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.
A ladder 5m long against a vertical wall 2m highfind the angle that makes with horizontal and vertical?
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
What is the supplement of 120 degrees?
60 degrees
What is sin 97 degrees?
all sin is sin97 degrees Fahrenheit = 36.1 degrees Celsius
What is the unit of sin θ?
Sin is a ratio and so has no units.
Is it possible to have a triangle whose angle measures are in the ratio 3 to 4 to 5 and whose side lengths are the same ratio?
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.
