Find the angle of intersection of the plane −3x−5y+3z=3−3x−5y+3z=3 with the plane −5x+3y−5z=−4−5x+3y−5z=−4. Answer in radians: and in degrees:

Skew lines(segments) are lines(segments) in 3 dimensions that do not intersect the given segment and are not parallel to it.  ae, bf, eg, and fh are your skew segments.  i hope that : )
