Question

Write the complementary, supplementary angles of ${75}^{\circ }$.

Answer 1

Complementary angles are those angles whose sum is ${90}^o$.

$={90}^o-{75}^o={15}^o$

Complementary angles of ${75}^o={15}^o$

Two angles are called supplementary angles, if their sum of two right angles $={180}^o$

$={180}^o-{75}^o={105}^o$

Supplementary angles of ${75}^o={105}^o$.
