If in triangle ABC, `cotA:cotB:cotC=30:19:16` show that `a:b:c=5:6:7`

In a triangle ABC, if cotA :cotB :cotC = 30: 19 : 6 then the sides a, b, c are

In a triangle ABC, if cotA :cotB :cotC = 30: 19 : 6 then the sides a, b, c are

In a triangle ABC, if cotA :cotB :cotC = 30: 19 : 6 then the sides a, b, c are

In a triangle ABC, if cotA :cotB :cotC = 30: 19 : 6 then the sides a, b, c are a) in A.P. b) in G.P. c) in H.P. d) None of these

If for a triangle ABC , cot A+cotB+cotC= sqrt3 ,then show that the triangle is equilateral.

In triangle ABC , if cotA, cotB, cotC are in A.P. then show that a^2,b^2,c^2 are also in A.P

If in any triangle ABC, cot A + cotB + cotC = sqrt(3) , prove that, the triangle is equilateral.

In triangle ABC, if cotA⋅cotC= 1 / 2 and cotB⋅cotC= 1 / 18 , then the value of tanC is

If in triangleABC ,3a^2=b^2+c^2 then cotB+cotC-cotA=
