In `DeltaABC` If, `(sin^2A+sin^2B+sin^2C)/(cos^2A+cos^2B+cos^2C)`=2 Then the triangle is

In a DeltaABC , If (Sin^(2)A+Sin^(2)B+Sin^(2)C)/(Cos^(2)A+Cos^(2)B+Cos^(2)C)=2 then the triangle is

In Delta ABC, if sin A+sin B+sin C=1+sqrt2 and cos A+cos B+cos C=sqrt2 then the triangle is

If A+B+C=180^(@)C then (sin 2A+sin 2B+sin 2C)/(cos A +cos B +cos C-1)=

In DeltaABC , if sin A + sin B + sin C= 1 + sqrt2 and cos A+cos B+cosC =sqrt2 then the triangle is

In DeltaABC , if sin A + sin B + sin C= 1 + sqrt2 and cos A+cos B+cosC =sqrt2 then the triangle is

In Delta ABC, if sin A+sin B+sin B+sin C=1+sqrt(2) and cos A+cos B+cos C=sqrt(2) then the triangle is

Statement-1: In a triangle ABC, if sin^(2)A + sin^(2)B + sin^(2)C = 2 , then one of the angles must be 90 °. Statement-2: In any triangle ABC cos 2A + cos 2B + cos 2C = -1 - 4 cos A cos B cos C
