〽Hola User_______________
⭐Here is Your Answer..!!!
______________________
↪Cartesian Coordinates of the system....!!
↪X = rcos⊙ and Y = rsin⊙
↪since here Radius (r) = 10 units and Theta (⊙) = 225°
↪there fore substituting we get as ..
↪X = 10 ( cos 225° ) = 10 * -1/ root 2 = -7.071
↪Y = 10 ( sin 225° ) = 10 * -1/root2 = = -7.071
↪the cordinates are as follows
↪(x,y) = (-7.071, -7.071 )
The graph is misleading because the sizes compared to the percentages are off. a more appropriate way to show the data would be with a bar graph.
Hope this helps!
