Question

If m N=42 degrees, then what is m k ?

​

Answer 1

`m\angle K=138^o`

Explanation:

we know that

The figure show a parallelogram

Remember that

In a parallelogram opposites angles are congruent and consecutive angles are supplementary

so

`m\angle N+m\angle K=180^o`

we have

`m\angle N=42^o`

substitute

`42^o+m\angle K=180^o`

`m\angle K=180^o-42^o=138^o`
