IF the sides of a triangle are ` x^2 + x+1 , x^2 -1 ` and ` 2x +1 ` then the greatest angle is

If the sides of trinangles are x^(2) + x+ 1,2 x + 1 , x^(-2) -1 where, x> 1, then the gratest angle is

The sides of a triangles are x^(2) +3x + 3, 2x+ 3 and x^(2) + 2x then the greatest angle of the triangle is

If sides of a triangles are in the ratio x: y : sqrt( x^(2) +xy + y^(2)) then greatest angle is

If the sides of a triangle are in the ratio x:y:sqrt(x^2+xy+y^2) , then the greatest angle is

If the angles of a triangles are in ratio 1: 2: 7 Then prove that the greatest side to the least side is ( sqrt5 + 1) : ( sqrt5-1)

If two sides of a triangle are roots of the equation x^(2)- 7x + 8 = 0 and the angle between these sides is 60^(@) then the product of inradius and circumradius of the triangle is

If two sides of a triangle are the roots of the equation 4x^2-(2sqrt6)x+1=0 and the included angle is 60^@ , then the third side is

The roots of x^2-2sqrt3x+2=0 represent two sides of a triangle. IF the angle between them is pi//3 , then the perimeter of the triangle is

Two sides of a triangle are given by the roots of the equation x^2-5x+6=0 and the angle between the sides is pi//2 . Then the perimeter of the triangle is
