Question

line wv is perpendicular to both line rs and line tu. which statement must be true about line tu? line tu is parallel to line rs. line tu is perpendicular to line rs. line tu has no slope. line tu has a slope of -5.

Explanation:

According to the property that if two lines are both perpendicular to a third line, then these two lines are parallel. Since line \(WV\) is perpendicular to both line \(RS\) and line \(TU\), line \(TU\) and line \(RS\) must be parallel.

Answer:

Line TU is parallel to line RS.
