(d) Complement = $29^{\circ}$, supplement = $119^{\circ}$
Given angle = $61^{\circ}$ Complement of $61^{\circ}$ = $90^{\circ} - 61^{\circ}$ = $29^{\circ}$ (As sum of the measures of complementary angles is 90 degrees, we can find 'one' by subtracting 'other' from $90^{\circ}$ ) Supplement of $61^{\circ}$ = $180^{\circ} - 61^{\circ}$ = $119^{\circ}$ (As sum of the measures of supplementary angles is 180 degrees, we can find 'one' by subtracting 'other' from $180^{\circ}$)
