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.)
