Answer

$ y^{\circ}$ may be any finite angle. Complement of $y^{\circ}$ = $ 90^{\circ} - y^{\circ}$ Supplement of $ y^{\circ}$ = $ 180^{\circ} - y^{\circ}$

Work Step by Step

$ y^{\circ}$ may be any finite angle. Complement of $ y^{\circ}$ = $ 90^{\circ} -y^{\circ}$ (As sum of the measures of complementary angles is 90 degrees, we can find 'one' by subtracting 'other' from $90^{\circ}$ ) Supplement of $ y^{\circ}$ = $ 180^{\circ} -y^{\circ}$ (As sum of the measures of supplementary angles is 180 degrees, we can find 'one' by subtracting 'other' from $180^{\circ}$)
