In the figure, ∠TVU = 90°. ∠TVW is 30° more than ∠UVW.
- What line is perpendicular to TV?
- Find ∠TVW.
(a)
Line UV or VU is perpendicular to TV.
(b)
∠UVW = 1 u
∠TVW = 1 u + 30
1 u + 1 u + 30° = 90° (Right angle)
2 u = 90° - 30° = 60°
1 u = 60° ÷ 2 = 30°
∠TVW
= 30° + 30°
= 60°
Answer(s): (a) UV or VU; (b) 60°
