Question

If mLM=25 and mLL=25, find mLJKM

50
18
162
117

Answer 1

`\displaystyle m\angle JKM = 50`

Explanation:

remember that,

if a side of a triangle expanded exterior so formed is equal to the sum of the two interior angles

so,

`\displaystyle m\angle JKM = 25 + 25`

simplify addition:

`\displaystyle m\angle JKM = 50`
