Question

cosa(tana+3)(3tana+1)=3 seca+10sina

Answer 1

Answer:

3 tan A =4, then value of √ 1-sin A/1+cos A is. Ask for details ... 3tanA = 4 tanA = 4/3 = perpendicular/base so, perpendicular = ... 3/5 so, \sqrt{\frac{1-sinA}{1 + ...

3tanA = 4 tanA = 4/3 = perpendicular/base so, perpendicular = 4 and base = 3 from Pythagoras
