Answer 1

$\huge \bf༆ Answer ༄$

Conversion from degree to radian ~

• $\boxed{ \sf{ \frac{\pi}{180} \times \theta }}$

• $\sf \dfrac{\pi}{180 } \times 90$

• $\sf \dfrac{\pi}{2} \: \: rad$

Conversion from radians to degree ~

• $\boxed{ \sf{ \frac{180}{\pi} \times \theta}}$

• $\sf \dfrac{180}{\pi} \times - \dfrac{ \pi}{5}$

• $\sf - 36 \degree$
