⭐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 )
Answer:
Step-by-step explanation:
Let sides of the triangle be 
Semi-perimeter (s) = 
Area of one tile 
So,
Area of 20 tiles 
Cost of polishing the floor at the rate of 2 rupees per sq.cm = 
To solve for x
bx=-7
divide b on both sides
x=-7/b
to solve for b
bx=-7
divide x on both sides
b=-7/x
