Well is this like history
I think the answer is x2 +64 but I hope you get it right good luck ! I hope it is 64 thanks

is in the 3rd quadrant... (It is also 210 degrees)
To find the reference angle (which is the distance to the x-axis)

(or 30 degrees)
sin
<span>(x + 6y) − (3x − 10y)
= x + 6y -3x + 10y
= -2x + 16y
Value of A: -2</span>
