Question

Look at quadrilateral LMJK in the circle shown below.
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°.
