Question

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

Answer 1

Answer:

$m\angle K=138^o$

Step-by-step 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

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

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