A+B+C+D+E=540°
4X+5+7X+6X+10+5X-5+4X+10=540
26X = 520
X = 520 : 26 = 20°
E = 4X + 10 = 80 + 10 = 90 °
Counter clockwise means it goes backwards so -90°
After the 90° counter clockwise rotation the coordinates are (4,-3)
The answer is a I believe
I hope this helped :)
The answer is 95 degrees because it is a vertical angle. This is actually a lot easier than it looks. Hope this helped.
