- We know, an exterior angle of a triangle is equal to the sum of its two opposite non-adjacent interior angles.
- Therefore, Angle V + Angle U = Exterior Angle T
![50 + angle \: \: u \: \: = 115 \\ = > angle \: \: u \: = 115 - 50 \\ = > angle \: \: u \: \: = 65](https://img.qammunity.org/2022/formulas/mathematics/high-school/sv0g7p5t77pal9krj635fh9wwbhalnwtrj.png)
Answer:
Angle U is 65°.
