Division Property of Equality

Step-by-step explanation:

from the second from last step, we have

2x = -36

if we divide both sides of the equation equally by 2, we get

(2x ) / 2 = (-36) / 2

x = -18 ..., which is exactly the last step that is given in the question

hence in order to get to the last step, we divide both sides of the equality by 2 (a non-zero number).

AKA  "Division Property of Equality"

No, the trapezoid HAS to be isosceles.

Step-by-step explanation:

For a trapezoid to be inscribed inside a circle, the trapezoid HAS to be isoseles. Given that it is not because of different angle measurements, it is not isoseles and is not able to be inscribed inside a circle.

Here is some extra reading if required:
