SolutionShow Solution. We know that for a triangle Δ ABC. ∠A + ∠B + ∠C = 180°. ∠B + ∠C = 180° - ∠A. ` (angleB+angleC)/2=90 - (angleA)/2`. `tan ( (B+C)/2) = tan (90^@-A/2)`. `=cos (A/2)`. Concept: Trigonometric Ratios of Complementary Angles.

For any triangle ABC, If `B=3C`, show that `cosC=sqrt((b+c)/(4c) For any triangle ABC, If `B=3C`, show that `cosC=sqrt((b+c)/(4c)) and sinA/2=(b-c)/(2c)`. For any triangle ABC, If `B=3C`, show that `cosC=sqrt((b+c)/(4c)) and sinA/2=(b-c)/(2c)`. Doubtnut is better on App. Given a triangle ABC, with angles 30,60,90 respectively and side lengths 1, 2, root (3) your premise falls down. But root (3) * Sin (90) + 2*Sin (60) = 2root (3) which doesn't = 1.
