x = -0.855x=0.855
y = -2.349y=2.349

Explanation:

Substitute r = 2.5r=2.5 and Theta = 250 in the following equations relating rectangular co-ordinates to polar co-ordinate-

x = r xx cos theta = 2.5 xx cos 250 = -0.855
y = r xx sin theta = 2.5 xx sin 250 = -2.349

Hence the rectangular co-ordinates of the given polar coordinates are

(-0.855, -2.349)
