We will use the trigonometric functions of the angle α = 35°.

"F_x = -F \\times cos \u03b1 = -(800 \\;N) cos 35\u00b0 = -655 \\;N"

"F_y = +F \\times sin \u03b1 = +(800\\;N) sin 35\u00b0 = +459 \\;N"

The vector components of F are:

"F_x = -(655 \\;N)i"

"F_y = +(459 \\;N)j"

We can write F as

F = -(655 N)i + (459 N)j
