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 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 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
