40+2x=180
2x=140
x=70
i use 2x since the angle measures of D and C are equivalent since it is an isosceles

Answer:
2 real solutions
Step-by-step explanation:
Since the degree of the polynomial is 2, then there are 2 solutions for the equation, but we don't know if they are both complex or both real.
Since the discriminant is
, then there are 2 real solutions.
