Answer:
Options (1) and (3)
Step-by-step explanation:
Exterior angles of a triangle is equal to the sum of two remote interior angles of the triangle.
In triangle JMK,
∠JMF is the exterior angle and angles ∠KJM and ∠JKM are the remote interior angles.
m∠JMF = m∠KJM + ∠JKM
Therefore, Options (1) and (3) are the correct options.
