The sine of an angle between 0 and 180 degrees is positive. The sine of an angle between 180 degrees and 360 degrees is negative. At 0, 180 and 360 degrees the sine is 0.
The sine is a periodic function with period 360 degrees, so angles differing by a multitude of 360 degrees have the same sine. Hence, for instance, the sines of the angles 0, 360, 720, ... are equal, namely 0.
In any right triangle the sine of one of the non-right angles will be positive, since these are greater than 0 and less than 90 degrees.

What is the angle of sine 0.151?
To find the angle whose sine is 0.151, you can use the inverse sine function (arcsin). Using a calculator, the angle is approximately 8.68 degrees or 0.151 radians. Keep in mind that sine is positive in both the first and second quadrants, so the angle could also be 171.32 degrees (or 3.00 radians) if considering the range of possible angles.
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 sine of angle of incidence divided by the sine of angle of refraction of equal optical density?
It is 1.
Why sine cannot measure angle larger than 45?
It can. The sine function is defined for all numbers--negative, 0, and positive. The function is periodic and repeats every 360 degrees.
What is sine in trigonometric function?
Sine of an angle (in a right triangle) is the side opposite of the angle divided by the hypotenuse.
Which angle has a negative sine and a positive cosine?
All the angles in 4th quadrant have positive cosine and negative sine e.g. 280,290,300,310...etc.
Why does Sine Theta equal Sine 180 minus Theta?
When you subtract theta from 180 ( if theta is between 90 degrees and 180 degrees) you will get the reference angle of theta; the results of sine theta and sine of its reference angle will be the same and only the sign will be different depends on which quadrant the angle is located. Ex. 150 degrees' reference angle will be 30 degrees (180-150) sin150=1/2 (2nd quadrant); sin30=1/2 (1st quadrant) 1st quadrant: all trig functions are positive 2nd: sine and csc are positive 3rd: tangent and cot are positive 4th: cosine and secant are positive

The sine of a 30 degrees angle equals what?
the sine of a 30 degree angle is 0.5
What is the size of an angle when the sine is 6352?
the sine of an angle can't be greater than 1.0
Is sine of an angle directly proportional to an angle?
No. The sine of an angle is not directly proportional to the angle. It is a function of the angle, but it is periodic, repeating every 360 degrees of the angle.
Why is the sine positive in quadrants 1 and 2?
In trigonometry, the sine function represents the ratio of the length of the side opposite an angle to the length of the hypotenuse in a right triangle. In quadrants 1 and 2, the angle is measured from the positive x-axis in a counterclockwise direction. Since the opposite side is positive in these quadrants and the hypotenuse is always positive, the sine function is positive. This is because the sine function is defined as positive when the opposite side is positive relative to the hypotenuse.
What is the sine of angle of incidence divided by the sine of angle of refraction of equal optical density?
It is 1.
Why sine cannot measure angle larger than 45?

How do you figure out the sine of a triangle?
An angle can have a sine ratio, not a triangle.
The sine of an angle is equal to what ratio?
Sine = opposite / hypotenuse
What is sine in trigonometric function?
Sine of an angle (in a right triangle) is the side opposite of the angle divided by the hypotenuse.
