Yes, the sine decreases, and so does the tangent.
Because a right angle will always measure 90 degrees no matter what the dimensions of the triangle are.
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.
Placing a question mark at the end of a phrase does not make it a sensible question. Try to use a whole sentence to describe what it is that you want answered.
It is an acute angle
When an angle has a measure of 120 degrees, it is an obtuse angle. When an angle is an obtuse angle its measure is between 90 and 180 degrees. That is: 90 degrees < obtuse angle < 180 degrees.
The trigonometric function of an angle gives a certain value The arc trigonometric function of value is simply the angle For example, if sin (30 degrees) = 0.500 then arc sine ( 0.500) = 30 degrees
it is the square root of 3 divided by 2
TRIGONOMETRIC FUNCTIONS OF ANY ANGLE
The period of a trigonometric function, since it depends on the angle of a ray centered in a unit circle, is 2 pi radians or 360 degrees.
you could use 160 degrees which will be in the tables and use the half angle formula
The fact that the same value is obtained when the angle in increased or decreased by any multiple of 2*pi radians (360 degrees).
The trigonometric functions are sine, cosine and tangent along with their reciprocals and the inverses. Whether the angle is acute or obtuse (or reflex) makes no difference).
Sine of an angle (in a right triangle) is the side opposite of the angle divided by the hypotenuse.
cos(22) is a trigonometric ratio and, if the angle is measured in degrees, its value is 0.9272
It is a trigonometric function, equivalent to the sine of an angle divided by the cosine of the same angle.
The sine of an angle is the cosine of its complement and conversely. The tan of an angle is the reciprocal of its complement.
cos(22) is a trigonometric ratio and, if the angle is measured in degrees, its value is 0.9272
