Question

Choose one angle and find three negative coterminal angles to that angle

Answer 1

Let us take the angle to be 30 degrees. So three positive co terminal angles are:

`\begin{gathered} 30+360=390 \\ 30+720=750 \\ 30+1080=1110 \end{gathered}`

Three negative co terminal angles are:

`\begin{gathered} 30-360=-330 \\ 30-720=-690 \\ 30-1080=-1050 \end{gathered}`

Therefore the positive angles co terminal to 30 are 390,750 and 1110 degrees and the negative angles are -330,-690 and -1050 respectively.
