Step 1: Note down the given important points

NOTE:   A + B = 90\degree

\cot B = \frac{3}{4}

Step 2:  Use the trigonometric ratios of complementary angles

EXAMPLE:   A + B = 90\degree

A = 90\degree - B

Apply the tan on both the sides

\tan A = \tan (90\degree - B) (since \cot B = \tan (90\degree - B)

\tan A = \cot B

So,   \tan A = \cot B = \frac{3}{4}
