If an angle measures D degrees or C radians, show that `(D)/(90)=(2C)/(pi)`.

What is the measure in degrees of an angle that is (pi)/(4) radians?

If D ,Ga n dR denote respectively the number of degrees, grades and radians in an angle, then (a) D/(100)=G/(90)=(2R)/pi (b) D/(90)=G/(100)=R/pi (c) D/(90)=G/(100)=(2R)/pi (d) D/(90)=G/(100)=R/(2pi)

IF n is a constant equal to the number of degrees in an angle measuring 3pi radians, what is the value of n?

In the sides of a triangle are in the ratio 1:sqrt(3):2, then the measure of its greatest angle is (a) pi/6 (b) pi/3 (c) pi/2 (d) (2pi)/3

The angles in a triangle are in A.P. and the ratio of the smallest angle in degrees to the greatest angle in radians is 60:phi Find the angle of the triangle in degrees and radians.
