The resultant of a certain system of forces has the x and y components shown in fig. 220. determine the components of this resultant with respect to n and t axes rotated 30 deg counterclockwise relative to the x and y axes.

First, you need to determine the resultant force and its angle. This one is real easy, since you only have one (x) and one (y) component. X = 300 and Y = 480 

1) sqrt (300^2 + 480^2) = ? (round your answer) 
2) tanθ = y/x Solving for θ: θ = tan^-1(y/x): θ = ? (round your answer) 

Now, you should have a resultant force value and its angle, from zero, in the first quadrant and between the Y and N axes. Draw yourself a diagram showing all of the axes, the resultant and the angles. You're going to have to do some very easy math to determine the angles between the Y and N axes and the resultant. Call these new angles α and β. α is the angle between N and the resultant and β is the angle between T and the resultant. Hint: one of them is 28 deg. 

Once you've gotten those figured, the Y and N axes become your new axis, ignore the X and Y. Find the X and Y components of the resultant (again). ? * cos(α) = 500 and ? * sin(β) = 266 (round your answers)

Anyone can me with these answers
