Answer:
(a) (-11.818, 2.084)
(b) (2.911, 2.443)
(c) (-14.387, -13.893)
Step-by-step explanation:
The generic expression for component form is ...
components = magnitude(cos(angle), sin(angle))
For repeated calculations, it works well to use a suitable calculator or spreadsheet.
(a) 12.0(cos(170°), sin(170°)) ≈ (-11.818, 2.084)
__
(b) 3.80(cos(40°), sin(40°)) ≈ (2.911, 2.443)
__
(c) 20.0(cos(224°), sin(224°)) ≈ -14.387, -13.893)
_____
In the attachment, the calculator is treating these as complex numbers. The component marked with "i" is the component in the y-direction.

Answer:
If 20 more soldiers join it would last 48 days
Step-by-step explanation:
if 80 soldiers need 84000 food for 60 days it means that in 60 days one soldier eats 84000/80= 1050 each
then 1050/60=17.5 meaning they need 17.5 food a day each,
adding 20 soldiers means 80+20= 100 soldiers
100*17.5=1750 food is eaten every day
84000/1750= 48 which means that 100 soldiers will eat 84000 in 48 days
