Question

Triangle K M L is shown. Line L K extends through point J to form exterior angle J K M.

Answer 1

Answer:

m∠KML +m∠MLK = m∠JKM is true

Step-by-step explanation:

m∠KML +m∠MLK = m∠JKM

Thereon that back it up:

Exterior angle m∠JKM is equal to the sum of the opposite interior angles m∠KML and  m∠MLK, the exterior angle follows that it must be larger than either of the opposite interior angles.

Answer 2

Answer:

m∠KML + m∠MLK = m∠JKM

Step-by-step explanation:

we know that

An exterior angle of a triangle is equal to the sum of the opposite interior angles

so

In this problem

m∠JKM ----> is an exterior angle

m∠KML and m∠MLK are the opposite interior angles to m∠JKM

see the attached figure

therefore

m∠KML + m∠MLK = m∠JKM
