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