Question

Each list shows the interior angle measures of a quadrilateral. Which set of measures describes a quadrilateral that cannot be inscribed in a circle?

69°, 103°, 111°, 77°

52°, 64°, 128°, 116°

42°, 64°, 118°, 136°

100°, 72°, 80°, 108°

I need help please ! ASAP

Answer 1

3rd option 42°, 64°, 118°, 136° cannot be inscribed in a circle because
For the quadrilateral of the type, this conjecture should be followed:

AngleA + AngleC = 180
AngleB + AngleD = 180

NB: Angle A&C and Angle B&D are opposite

Answer 2

I got it :) thank you so much.
