What are different kinds of angle differentiate each angle?
Acute angle in the range (0, pi/2) radians = (0, 90) degrees.Right angle = pi/2 radians = 90 degrees.Obtuse angle in the range (pi/2, pi) radians = (90, 180) degrees.Straight angle = pi radians = 180 degrees.Reflex angle in the range (pi, 2*pi) radians = (180, 360) degrees.Full turn = 2*pi radians = 360 degrees.
How do you calculate the length of an arc of a circle?
The length of the arc is equal to the radius times the angle (angle in radians). If the angle is in any other measure, convert to radians first. (radians = degrees * pi / 180)
What is the measure of an angle that is 93 degrees?
93π/180 radians (about 1.623 radians)
What is the exact value of sin150?
sin150 is 0.5 Remember that 150o is 5π/6 radians and the reference angle is π/6 or 30o. sin30 is 0.5
What is the difference between a zero angle and a straight angle?
A straight angle is pi radians (180 degrees) so the difference is pi radians.
What is the reference angle in radians for 876 degrees?
!
Why is 90 degrees taken as angle of reference in trigonometry?
It is not. The angle of reference is 2*pi radians or 360 degrees.
Are reference angles and radians the same?
No. A radian is a measure of an angle, it is not, itself, an angle. Degrees and radians are measures of angles and the two measures are related by the following conversion: 180 degrees = pi radians
What is the angle 135 in radians?
There are 2.356 radians in 135 degrees of angle.

An angle that egauls 180 degrees?
If you are looking for an angle in radians, then pi radians equals 180 degrees.
How would an angle in radians be converted to an angle in degrees?
Multiply radians by (180/pi), roughly 57.3, to get degrees.
How do you calculate the length of an arc of a circle?
The length of the arc is equal to the radius times the angle (angle in radians). If the angle is in any other measure, convert to radians first. (radians = degrees * pi / 180)
A wire of length 20cm is bent so as form arc of circle of radius 12cm what is the angle subtended at the center in radians is?
When the angle is measured in radians arc_length = angle x radius. So, 20cm = angle x 12cm => angle = 20cm / 12cm ~= 1.67 radians
What is the measure of an angle that is 93 degrees?
93π/180 radians (about 1.623 radians)
What is the exact value of sin150?
sin150 is 0.5 Remember that 150o is 5π/6 radians and the reference angle is π/6 or 30o. sin30 is 0.5
What is the difference between a zero angle and a straight angle?
A straight angle is pi radians (180 degrees) so the difference is pi radians.
