The answer is 2x-5 (I hope that's what you meant)
I^22 equals to -1 since i^2 is negative one
Hi i think the answer to this is a=0
It would be this. -2x and 2x cancel out, leaving you with fx=-1
Answer:
80
Step-by-step explanation:
Sum of interior angles of a polygon = (n-1)x180= (6-2)x180=720
Since this looks like a regular hexagon each interior angle =720/6=120
Hence the inside angle touching the line is 120 (inside the hexagon)
Since one side of the hexagon is parallel to the line, y and 20 form adjacent angle, sum 180,
Then y= 180-20=160
Then x=360-(160+120)=80 because sum of all angles round a point=360
