Answer:
m∠KML+m∠MLK=m∠JKM
Step-by-step explanation:
we know that
The sum of the interior angles of triangle must be equal to 180 degrees
m∠KML+m∠MLK+m∠MKL=180° -----> equation A
m∠JKM+m∠MKL=180° -----> by supplementary angles (form a linear pair)
m∠MKL=180°-m∠JKM ----> equation B
substitute equation B in equation A
m∠KML+m∠MLK+(180°-m∠JKM)=180°
m∠KML+m∠MLK=m∠JKM
