Answer:
C ≈ 22.1°
Step-by-step explanation:
The law of cosines formula is given. Solving it for C, we find ...
C = arccos((a^2 +b^2 -c^2)/(2ab))
where a and b are the sides adjacent to the angle.
Then we have ...
C = arccos((14^2 +19^2 -8^2)/(2·14·19)) = arccos(493/532)
C ≈ 22.1°

If you have a fair number of these to do, a spreadsheet is a useful tool. There are also triangle solver apps on the web or your local smart platform that will do this, too.
I believe by intersect, you mean perpendicular. Also, skew lines can be on parallel planes and still intersect. If they intersected, then the degrees must be 90
X= 8sqrt(2)
sorry i don’t know how to type the radical, but where the “sqrt” is the would be the symbol
