Answer:
- 80·cos(43°)
- 80·sin(43°)
- horizontal: 58.5 N
- vertical: 54.6 N
Explanation:
You want the horizontal and vertical components of the force described as 80 N at an angle of 43° above the horizontal.
Horizontal component
The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
This tells us ...
Adjacent = Hypotenuse·Cos
horizontal component = (80 N)·cos(43°)
horizontal component = 58.5 N
Vertical component
The relevant trig relation is ...
Sin = Opposite/Hypotenuse
This tells us ...
Opposite = Hypotenuse·Sin
vertical component = (80 N)·sin(43°)
vertical component = 54.6 N

Additional comment
Your post shows you already know the formulas for the horizontal and vertical components. All you need to do is evaluate the expressions using your calculator. (Make sure it is set to degrees mode.)
