Three forces are acting on an object located on an inclined

Three forces are acting on an object located on an inclined plane.The incline is tilted at an angle θ=34°.One can show that the angle shown in the diagram is this same θ.Assume the +x direction is up and to the right.Assume the +y direction is up on to the left.
What is the component of the net force in the direction parallel to the incline (the x-axis)?
What is the component of the net force in the direction perpendicular to the incline (the y-axis)?
The three forces are:F1 = 61.35 N; F2 = 74.0 N; and F3 = 8.0 N.

x方向的净力为:F3-F2sinθ
y方向的净力为:F1-F2cosθ

我题目的大致意思也不知道说的对不对,是问XY轴力的组成部分么?那么给力的大小干什么。。。。x轴上就是F2在X轴负方向上的分力和力F3的合力,Y轴上就是F2在Y轴负方向上的分力和力F1的合力,求大小不会再追问吧
