How do you find the size of an angle when you have only the sine of the angle?

You use the arcsine or sin-1 function. For any value of sin(X), the function will return a value for the angle in the range [-pi/2, pi/2]. There are, however, infinitely many angles which will have the same value for sine. They are
X + 2k*pi and (2k+1)*pi - X radians where k is any integer.
If you still work with degrees, the answers are
X + 360k and (2k+1)*180 - X degrees.

What is Law of the sine?
The law of sines is a statement about arbitrary triangles in the plane.The law of sines states that in any right triangle, the ratio of the opposite side length to the length of the hypotenuse (relative to an acute angle) is always relative to the size of the angle. Put more simply, it means that if you take the sine of an angle, the value will be equal to the length of the opposite side divided by the length of the hypotenuse. The practical application of this is when you know the length of only one side and the measure of one angle (other than the right angle) you can determine the other sides and the remaining angle.The law of sines states that in any right triangle, the ratio of the opposite side length to the length of the hypotenuse (relative to an acute angle) is always relative to the size of the angle.

What does supplement mean in math?
A supplement to an angle in Geometry is a second angle with a size equal to the difference between 180 degrees and the size of the first angle. If the size of two angles is 180 degrees, then the angles are 'supplementary".
If a clock shows 9 o'clock which size is the inside angle between the two hands?
the angle size is 90 degrees
What is the size of an angle when the sine is 6352?
the sine of an angle can't be greater than 1.0
What is the size of an angle when the sine is point6352?
39o26' (to the nearest minute) Explanation: Let the angle = θ sinθ = 0.6352 To find the angle of sinθ, you must apply sin-1 to sinθ. sin-1θ = 39o26'5.35"
What is the cosine of angle b?
I could answer that for you in a snap if I knew the size of angle 'b'.Without that information, no answer is possible.Wait! There is an answer. Not a useful one, but an answer nonetheless.The cosine of angle 'b' is the square root of [ 1 minus the square of the sine of angle 'b' ] .You heard it here first.
How do you find the size of an angle on a rhombus?
with a protractor
When would you use sine or sine-1 on your calculator?
On a right-angled triangle, let one of the angles that is not the right angle be x. 'Sine x' is the length of the side opposite (not touching) x divided by the hypotenuse (longest side or the side that is opposite/not touching the right angle). This gives you the ratio or relationship between these two sides.Sine-1 is the opposite; if you know the two sides (hypotenuse and opposite side) related to x, sine-1 of the opposite side divided by the hypotenuse will give you the size of angle x.If this confuses you, sorry but it would have been much easier with a diagram. Wait until you learn trigonometry. There's only so much I can do using text.
How do you find the size of the angle in a quadrilateral?
Use a protractor.
What is the size of one angle on a 19 sided polygon?
An individual angle can have any size you like. The only constraint is on the sum of all 19 angles.
What device or tool would you use to find the size of an angle?
A protractor.
How do you find out the size of a regular polygon?
Divide the number of sides into 360 which will give you the exterior angle and subtract this angle from 180 which will give you the interior angle.

How do you determine the measurement of a missing angle in a angle?
To find the measure of an angle, you need to know the size of the entire angle and the other angles within the angle. Then, you subtract the smaller, known angles from the entire, large angle and you should get the measure of the missing angle.
