1. The problem asks to identify the term that describes segment WU in triangle WVT given the angles at vertex W. 2. Definitions: - An **angle bisector** divides an angle into two equal parts. - A **median** connects a vertex to the midpoint of the opposite side. - An **altitude** is a perpendicular segment from a vertex to the opposite side. 3. Given angles at W are 21° and 24° between WU and the sides WV and WT respectively. 4. Since the angles are not equal (21° \neq 24°), WU does not bisect the angle at W, so it is not an angle bisector. 5. There is no information that WU is perpendicular to VT, so it is not necessarily an altitude. 6. There is no information that U is the midpoint of VT, so WU is not necessarily a median. 7. Therefore, the correct description for WU is **none of these**. Final answer: none of these
