Okay, let's solve this step-by-step:

* Points J, K, L, M have polar coordinates:

J (6, 130°)

K (6, 160°)

L (6, 200°)

M (6, 250°)

* To find the angle between two points, we subtract their theta values (polar angle coordinates).

* Angle KJM = 160° - 130° = 30°

* Angle KLM = 250° - 200° = 50°

* Sum of angles KJM and KLM = 30° + 50° = 80°

* Since the sum of angles in any triangle is 180°, and we have 80°, the remaining angle must be 180° - 80° = 100°.

* Therefore, the sum of angles KJM and KLM is 180°.

Does this make sense? Let me know if you have any other questions!
