Webb11 mars 2024 · Click here 👆 to get an answer to your question ️ Prove that 2tan 50º = tan 70° - tan20 ... tan70 - tan50 = tan20 + tan50. So tan70 = tan20 + 2tan50. Complementary angles: tan70=cot20. tan70tan20=cot20tan20=1. Tangent difference angle formula: tan(a−b)=tana−tanb1+tanatanb. WebbLet A = tan (20), B=tan (50), C=tan (70) Because C = [sin (20+50)] / [cos (20+50)] = (A+B)/ (1-A*B) it is clear, if both, numenator an d denominator, are divided by cos (20)*cos (50) Then should be A+2B = C* (1 - A*B) + B …
