Question

Write the supplement of each of the following angles:
(i) ${54}^{\circ }$ (ii)${132}^{\circ }$ (iii) ${138}^{\circ }$

Answer 1

We know that two angles are supplement to each other if their sum if ${180}^{\circ }$. Therefore,
(i) Supplement of ${54}^{\circ }$ is $({180}^{\circ }-{54}^{\circ })={126}^{\circ }$
(ii) Supplement of ${132}^{\circ }$ is $({180}^{\circ }-{132}^{\circ })={48}^{\circ }$
(iii) Supplement of ${138}^{\circ }$ is $({180}^{\circ }-{138}^{\circ })={42}^{\circ }$
