Question

Are the following pairs of angles supplementary?
`3/10` of a right angle and `4/15` of two right angles.

Answer 1

`3/10` of a right angle and `4/15` of two right angles

⇒ `3/10` of 90° and `4/15` of 180°

⇒ 27° and 48°

No, there are not supplementary angles as their sum is not 180° (27° + 48° = 75°)
