The value of an angle is D in degree and R in radian. Find the value of `D/R`.

The value of angle r in figure below is

Express value of radians in degrees.

The measures of an angle are D and R in degree and radian respectively. Then R/D is equal_____

If the measure of an angle is D and R respectively in degree and radian, prove that D/9=(20R)/pi

If the sum and difference of two angles are 22/9 radian and 36^(@) respectivly, then the value of smaller angle in degree taking the value of pi as 22/7 is :

(i) The angle of a triangle are in A.P and the greatest angle of the triangle is double the least angle , find the greatest angle in radians.(ii) The angle of a traingle are in A.P and the number of degree in the least to the number of radian in the greatest is as 60^(pi) find the angles in degree and radians.
