Figure$1$ of $1$

Two forces act on a screw eye attached to a vertical wall. The x axis points out of the screen. The y axis points horizontally to the right. The z axis points vertically upward. The wall is parallel to the x z plane. The screw eye is located at the origin. Force F subscript $1$ equal to $300$ newtons lies in the second octant. The projection of this force vector onto the x y plane makes an angle of $45$ degrees with the positive y axis. The angle between this force vector and its projection onto the x y plane is theta. Force F subscript $2$ equal to $500$ newtons lies in the fifth octant and makes an angle of $60$ degrees with the positive x axis, $45$ degrees with the positive y axis, and $120$ degrees with the positive z axis.
