Calculating Resultant Force from Two Forces at a Point

[treverd]

Homework Statement

Two forces, F1 and F2, act at a point. The magnitude of F1 is 9.80 , and its direction is an angle 65.0 above the x-axis in the second quadrant. The magnitude of F2 is 5.00 , and its direction is an angle 52.3 below the x-axis in the third quadrant.

What is the x-component of the resultant force?




What is the y-component of the resultant force?




What is the magnitude of the resultant force?

Homework Equations

Fcos(\vartheta) for X-component

Fsin(\vartheta) for y-component

\sqrt{X-comp^{}2/y-comp^{}2}

The Attempt at a Solution

I take
9.8*Cos(180-65) for X-component but that's wrong

what else should I try.
Thanks a lot.

there's 2 forces, why did you only calculate the x-component of the one force. It wants the sum of the x components of both forces.

This is just what I started on. If I don't get this part right then I won't be able to get the rest right.
