Hope it heled.
Please note this rotation just allows you to turn (x,y) to (y,x)
Here are the rotation rules: 90° clockwise rotation: (x,y) becomes (y,-x) 90° counterclockwise rotation: (x,y) becomes (-y,x) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
ΔQVS is similar to ΔRTS
.
<u>Solve x:</u>
6x = 80
x = 40/3
x = 13 1/3
.
Answer: x = 13 1/3
