Circle Properties## Brent, can you please help me

## Question #8 requires a rule

Question #8 requires a rule regarding cyclic quadrilaterals. These are quadrilaterals that are inscribed in a circle.

For all cyclic quadrilaterals, any two angles that are opposite each other will add to 180 degrees.

So, for question #8, x + 135 = 180 degrees, so x = 45

For the GMAT, you don't need to know anything about cyclic quadrilaterals. So, you can disregard that question.

Sorry, I didn't notice question #8 when I posted the link. I have edited the link accordingly.
