Based on this figure which statement proves that the opposite angles of an inscribed quadrilateral are supplementary?

Angle KJM is a, angle KLM is b, and a + b + angle JKL + angle LMJ = 360°.

Angle KLM is a, angle KJM is b, and a + b + angle JKL + angle LMJ = 360°.

a = 2 × angle KJM, b = 2 × angle KLM, and a + b = 360°.

a = 2 × angle KLM, b = 2 × angle KJM, and a + b = 360°.
