3 cot A =4 check wheather 1- tan^2A\1+tan^2A= ​

Answer 1

Answer:

$\frac{7}{25}$

Step-by-step explanation:

$\\3 cotA =4\\\\cotA=\frac{4}{3}\\\\cotA=\frac{adj}{opp}=\frac{4}{3}\\\\hypotenuse_by_pythagorus_theorem:\\\\hyp=5\\\\tanA=\frac{opp}{adj}=\frac{3}{4}\\\\tan^{2}A=\frac{9}{16}\\\\by_subsituting\\\\\frac{1-tan^{2}A}{1+tan^{2}}\\\\the_answer_will_be\\\\\frac{7}{25}\\if it ishelpful make me brilliant$
