Answer:
9x^2+3x-90
81x+3x-90
84x-90 final answer
Step-by-step explanation:
AC is not the bisector of angle BAD. AC made both sides a triangle and every triangles angles have to add to 180 degrees. So 115+30= 145 meaning angle DAC is 35 degrees. So AC cuts through BAD but one side is 30 degrees and the other is 35(DCB and DAB are the same angle…they both have to add up to 65 degrees)

Answer:
Coordinates of E is (-2,7)
Step-by-step explanation:
Midpoint = ((x1+x2)/2,(y1+y2)/2)
xK = (xW + xE)/2 => xE = 2xK - xW = 2(0) - 2 = -2
yK = (yW + yE)/2 => yE = 2yK - yW = 2(3) - (-1) = 7
