Question

find tu. enter your answer as a number.
answer

Explanation:

Step1: Identify the triangle property

In triangle \( TWV \), \( WT = WV \) (marked with equal segments), and \( WU \) is perpendicular to \( TV \). By the perpendicular bisector theorem, a perpendicular from the vertex to the base of an isosceles triangle bisects the base. So \( U \) is the midpoint of \( TV \).

Step2: Calculate \( TU \)

Given \( VU = 4 \), and \( U \) bisects \( TV \), so \( TU = VU \). Thus \( TU = 4 \).

Answer:

4
