It seems you can fill in the table with the equation y = 3 * x
x = 1 then y = 3
x = 3 then y = 9

x^-m=1/(x^m)
6 times x^-2=6 times 1/(x^2)=6/(x^2)=
Angle B is also 54° because they are vertically opposite angles.
Now, you do 54+54=108 and then 360-108=252. (The angles should always add up to 360, so remember that) Because angles C and D are also vertically corresponding angles, they add up to 252, and each measure 126°
