x, y, z are integer that are side of an obtuse-angled triangle. If xy = 4, find z.

The side opposite to an obtuse angle of a triangle is :

If 2x = 3y = 4z, find x:y: z.

If the sides of a triangle are 3, 5, and 6, prove that the triangle is obtuse - angled triangle and find the obtuse angle.

If the sides of a triangle are 3,5, and 6, prove that the triangle is obbtuse - angled triangle and find the obtuse angle.

Let x,y an z be positive real numbers. Suppose x, y and z are the length of the sides of triangle opposite ot its angles, X,Y and Z respectively.If "tan" (X)/(2)+"tan"(Z)/(2)=(2y)/(x+y+x) then which of the following statement is/are TURE ?

The points A(x,y), B(y, z) and C(z,x) represents the vertices of a right angled triangle, if

The points A(x,y), B(y, z) and C(z,x) represents the vertices of a right angled triangle, if

The points A(x,y), B(y, z) and C(z,x) represents the vertices of a right angled triangle, if

The points A(x,y), B(y, z) and C(z,x) represents the vertices of a right angled triangle, if
