Question

Identify whether the following pairs of angles are complementary or supplementary:
${130}^o,{50}^o$

Answer 1

If sum of two angles is ${180}^o$, then they are called supplementary angles. If sum of two angles is ${90}^o$. then they are called complementary angles.
${130}^o+{50}^o={180}^o$ These are supplementary angles.
