If the 49.5 is in radians, then sin 49.5 ≈ −0.693 and so yes.
If the 49.5 is in degrees, then sin 49.5o ≈ 0.760
If the 49.5 is in gradians, then sin 49.5 ≈ 0.702
If the 49.5 is in some other angle measurement, then you'll have to decide as I only know Degrees, Radians and Gradians angle measures.
In Degrees, one full turn is 360o
In Radians, one full turn is 2π radians ≈ 6.283 radians
In Gradians, one full turn is 400 gradians.
Radians are most useful in calculus.
In fact you've used radians without realising it:
The length of an arc of angle θ of a circle of radius r is θr when θ is measured in radians; the length of an arc of a circle round one full turn (ie the circumference of a circle) is θr = 2πr since one full turn is 2π in radians.

Rule for multiplying integers?
Positive x negative = negative (Negative x positive = negative) Positive x positive = positive Negative x negative = positive So if the signs are the same the answer is positive and if they are different it is negative.
Is Sin a negative function or positive?
negative
Can reference angles be negative?
Certainly. A negative angle is simply clockwise instead of counterclockwise from the zero angle, but this is usually not indicated as such on a drawing.
Why is the tangent positive on quadrant III?
The tangent function is equal to the sine divided by the cosine. In quadrant III, both sin and cos are negative - and a negative divided by another negative is positive. Thus it follows that the tangent is positive in QIII.
A organized list of possible combinations?
Should be used where possible.
Is it possible to have negative decimal numbers?
yes, it is possible to have a negative decimal.
Is it possible to travel at a negitave speed?
Negative speed isn't possible, but negative velocity is.
If my child has A negative blood and I have o positive her father has ab negative is this possible?
Yes it is possible...
Is it possible to have a negative variance?
No.
What is the negative of possible?
Impossible.
Is it possible to draw a circle of negative radius?
Radii are always positive. No, it is not possible to draw a circle with negative radius.
Is it possible to have a negative absolute pressure?
No. "Absolute" means non-negative.
Can you be pregnant and the test negative?
It is possible to be pregnant and the test negative, but not likely.
Is it possible to have a negative variable?
Yes
Is it possible for a coefficient of variation to be negative?
Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.
Is it possible to find the square root of a negative number explain why or why not?
This is not possible, because any number squared would be positive, not negative.
Is it possible for a negative number to be greater thatn a positive number?
this is not possible
