See below

For calculating central angle, use the formula

$\frac{Given value}{Total value} \cdot 360^{\circ}$ $("Given value") / ("Total value") * 360^@$

Putting your values, we get

$= \frac{320}{1440} \cdot 360^{\circ}$ $= 320/1440*360^@$

Now simplify it

$= 320/(cancel1440^4)* cancel360^@$

$= 320/4 ""^@$

$= (cancel320^80)/(cancel4) ""^@$

$= 80 ^@$

So, the central angle for the component is $80^@$ .
