Answer:
x ’= 368.61 m,  y ’= 258.11 m
Explanation:
To solve this problem we must find the projections of the point on the new vectors of the rotated system  θ = 35º
      x’= R cos 35
      y’= R sin 35
     Â
The modulus vector can be found using the Pythagorean theorem
      R² = x² + y²
      R = 450 m
we calculate
      x ’= 450 cos 35
      x ’= 368.61 m
      y ’= 450 sin 35
      y ’= 258.11 m
