Question

IF A + B = 90°, Cot B =3/4
then tan A ?​

Answer 1

Answer:

A =120

Step-by-step explanation:

A+B =90

A+3/4=90

A=90*4/3

A=120

Answer 2

Answer:

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

Step-by-step explanation:

$Given \:A+B = 90\degree$

$\implies B = (90 - A)\: ---(1)$

$Cot B = \frac{3}{4}\:(Given)$

$\implies cot(90-A) = \frac{3}{4}\:[From \:(1)]$

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