j- 120 degrees
k- 38 degrees
For j...
The formula to find the total interior angle measurement for one angle is [tex]\frac{(x-2)180}{2}[/tex]. "x" is the number of angles. So in this case [tex]\frac{(6-2)180}{2}[/tex].
For k...
opposite vertical angles are equal, so the measurement provided will be the same for k.
