The sides of a triangle are in `A.P` and the greatest angle exceeds the least by `90^(0)` .The sides are in the ratio

If the sides of a triangle are in A.P. and the greatest angle of the triangle exceeds the least by 90^(@) , then sine of the third angle is

If the sides of a triangle are in A.P., and its greatest angle exceeds the least angle by alpha , show that the sides are in the ration 1+x :1:1-x , , where x = sqrt((1- cos alpha)/(7 - cos alpha))

The angles of a triangle are in AP and the greatest angle is double the least. What is the ratio of angles in the radian measure ?

(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.

If the sides of a triangle are 13,7,8 then the greatest angle of the triangle is

The sides of a triangle are in A.P.and the greatest angle is double of smallest angle.The ratio of its sides is

If the lengths of the sides of a triangle are in AP and the greatest angle is double the smallest, then a ratio of lengths of the sides of this triangle is

The angles of a triangle are in A.P. the least being half greatest. Find the angles.
