- Suppose the x- and y-axes are routed through an acute angle to produce the new X- and Y-axes. A point P P in the plane can be described by its xy-coordinates (x,y) or its XY coordinates. These coordinates are related by the following formulas. x= X= y= Y=arrow_forwardIn the figure, we see that mRS-=mVT-=0. Find the equation that relates r,s,andt if it is known that RSTV is a parallelogram. _arrow_forward
