In the figure, ∠TVU = 90°. ∠TVW is 33° 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 + 33
1 u + 1 u + 33° = 90° (Right angle)
2 u = 90° - 33° = 57°
1 u = 57° ÷ 2 = 28.5°
∠TVW
= 28.5° + 33°
= 61.5°
Answer(s): (a) UV or VU; (b) 61.5°
