Answer:
To convert the degrees to radians
[tex]144^{\circ}[/tex]we know that,
Radian is equivalent to the angle subtended at the centre of a circle by an arc equal in length to the radius.
we get that,
[tex]1\text{ radian}=\frac{180^{\circ}}{\pi}\text{ degrees}[/tex]That is,
[tex]1\text{ degree}=\frac{\pi^{}}{180^{\circ}}\text{ radians}[/tex]we get that,
[tex]144^{\circ}=144^{\circ}\times\frac{\pi}{180^{\circ}}\text{ radians}[/tex][tex]=\frac{4}{5}\pi\text{ radians}[/tex][tex]=0.8\pi\text{ radians}[/tex]Answer is: 0.8
