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 is sine in trigonometry?
The sine of one of the acute angles in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.
Does a rhombus has obtuse angles?
Yes. Two obtuse angles, of equal measure.Yes. Two obtuse angles, of equal measure.Yes. Two obtuse angles, of equal measure.Yes. Two obtuse angles, of equal measure.
What does the sine of an angle tell us?
In a right-angled triangle, the sine of one of the smaller angles is the ratio of the length of the opposite side to the length of the longest side.
Why can't a pair of obtuse angles be vertical angles?
Because they are obtuse angles!
An obtuse triangle can have two obtuse angles?
No an abtuse triangle can not have two obtuse angles
What is sine in trigonometry?

The ratio of the lengths of two sides of a right triangle?
Proportional to the sine of the angles opposite them.
How does one differentiate between the sine rule and the sine ratio?
The sine rule(also known as the "law of sines") is: a/sin A = b/sin B = c/sin C where the uppercase letters represent angles of a triangle and the lowercase letters represent the sides opposite the angles (side "a" is opposite angle "A", and so on.) Sine Ratio(for angles of right triangles): Sine of an angle = side opposite the angle/hypotenuse written as sin=opp/hyp.

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.
Why can't a pair of obtuse angles be vertical angles?
Because they are obtuse angles!
An obtuse triangle can have two obtuse angles?
No an abtuse triangle can not have two obtuse angles
Do rectangles have obtuse angles?
A rectangle has no interior obtuse angles.
How many obtuse angles in a parallelogram?
It has two obtuse angles
What are the angles in an obtuse triangle?
An obtuse triangle has 1 obtuse angle and 2 acute angles
Are the angles in an octagon obtuse?
No, the angles in an octagon are not necessarily obtuse. An octagon can have a mix of acute, obtuse, and right angles depending on its shape and dimensions.
