Solve Vector Force Problem with Trigonometry: Step-by-Step Guide"

[neurotikfisch]

Having some trouble with this exercise; help appreciated! :]

Homework Statement

Homework Equations

Fx + Fy = F
Pythagorean Theorem

The Attempt at a Solution

basically I used the trigonometric identities to conclude that the necessary force was 69.28N and the Y component of the force was 34.90N


I'm sure I'm going to feel pretty dumb after it clicks, but I'm not sure what to do about the 20deg angle that's thrown into the problem. Should I have used that in my trigonometric calculations?

no, it makes no difference to the question asked

(it will of course affect the effect of the force … but the question doesn't ask for that! )
