We know that the measure of the complementary angle of $x^{\circ }$ is equal to ${90}^{\circ }-x^{\circ }$.

(i) Measure of the complementary angle of ${22}^{\circ }={90}^{\circ }-{22}^{\circ }={68}^{\circ }$

(ii) Measure of the complementary angle of ${63}^{\circ }={90}^{\circ }-{63}^{\circ }={27}^{\circ }$
