That will depend on the plus or minus value of 12 which has not been given.
We don't know and we can't calculate it, until the value of 'x' is given.
The discriminant is 9.
A = C = 180 - B = 80 So A + C = 160

Given ef is the midsegment of isosceles trapezoid abcd bc equals 17x ef equals 22.5x plus 9 and ad equals 30x plus 12 find ad?

9 degrees

160 degrees.
ba = 32 CD = 9x + 5 The best we can do in this case is write x in relation to it's original equation: x = (CD - 5)/9 because we have no way of relating a, b, c, and d from the given information.
No; it is false. The sum of all the angles of a quadrilateral always equals 360o.
