Question

If A + B =90 , cot B =3 / 4, then find tan A ?

Answer 1

Answer:

$tanA = \frac{3}{4}$

Step-by-step explanation:

$cotB =\frac{3}{4}\:---(1)\\and \: A+B = 90\:(given)$

$\implies A = 90\degree - B$

$\implies tan A = tan (90\degree - B)$

$\implies tanA = cotB$

$\implies tanA = \frac{3}{4} \: [ From \:(1) ]$

Therefore,

$tanA = \frac{3}{4}$
