Question

Which equation could be used to solve for the measure of angle O?

Circle N is shown with a quadrilateral OPQR inscribed inside it. Angle O is labeled x degrees. Angle P is labeled y degrees. Angle Q is labeled z degrees. Angle R is labeled w degrees.

x + z = 180

x + y = 180

x − (y + z) = 360

x + y + z = 360

Answer 3

I'd go with x+y+z=360
A circle measures 360 degrees, x y and z would come to about that value when plugging in numbers you would have say x+145+120=360 combine the like terms x+265=360 solve for x. x=45 (not saying thats the answer but it would be an example)
