If this regular decagon is rotated counterclockwise by 3
times the smallest angle of rotation, which vertex will
be in the top position?

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

9 x 8 divided by (5-3)=36

i believe that the slope of the line is -5
