congruent line segment
parallel, perpendicular, and intersecting lines
lesson: perpendicular b

Explanation:

Step1: Use the Hypotenuse - Leg (HL) Congruence Theorem

Since \(ST = SR = 81\) and \(SU\) is a common perpendicular, \(\triangle TSU\cong\triangle RSU\) (by HL theorem). So \(TU = RU\).

Step2: Calculate \(TU\)

Given \(RU = 64\), so \(TU=64\)

Answer:

\(64\)
