Find out value of sin 45?
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.
What is the sin theta of 30 degrees?
Sin theta of 30 degrees is1/2
What is the sin of 10 degrees?
The sine of 10 degrees is approximately 0.1736. This value can be found using a scientific calculator or trigonometric tables. In the context of a right triangle, it represents the ratio of the length of the side opposite the angle to the length of the hypotenuse.
What is the cosine of 120 degrees?
Cos(120) = -0.5
What does sin 28 look like?
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.
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.
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.
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 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 the ratio of side opposite over hypotenuse?
It is the Sine(Sin) ratio. Sin(angle) = o/h
What is sin 57 degrees?
sin 57 degrees
What is sin 97 degrees?
all sin is sin97 degrees Fahrenheit = 36.1 degrees Celsius
What is the sine of 50 degrees in radians?
The sine of an angle returns a dimensionless ratio, not an angle, which can be measured in either degrees or radians (or gradians, if you want to get technical). Sines and other trigonometric functions except angles as input to return this ratio. The sine of 50 degrees is .766044443119. The sine of 50 radians is -.262374853704.
