Webb29 nov. 2024 · Prove that : tan70 o = tan20 o + 2tan50 o. Solution Hint: Now cross-multiply and simplify the above fraction we get the required result. Question 9. Question 10. If tan A = k tan B, then show that: Solution Hint: tan A = k tan B Now apply componendo and dividendo and using trigonometric formulas. 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 …
