Theorem 1: Radian is a constant angle

Express the following angles in radians. (i) 120^(@) " " (ii) -600^(@) (iii) -144^(@)

Express the following angles in radians. (i) 120^(@)(ii)225^(@)(iii)945^(@)

Convert the following angles into degrees: a) 2 radian b) 22 radian

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:pi Find the angle of the triangle in degrees and radians.

The angles of a triangle are in AP and the ratio of the number of degrees in the least to the number of radians in the greatest is 60:pi . Find the angles in degree and radians.

The unit of plane angle is radian , hence its dimension are

(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. (iii) The angles of a traingle are in A.P and one of them is 80^(@) . Find all the angle in sexagesimal system. (iv)The angle of a traingle are in A.P and the greatest is 84^(@) . Find all the three angle in radians.
