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}
