In the figure, ∠RTS = 90°. ∠RTU is 32° more than ∠STU.
- What line is perpendicular to RT?
- Find ∠RTU.
(a)
Line ST or TS is perpendicular to RT.
(b)
∠STU = 1 u
∠RTU = 1 u + 32
1 u + 1 u + 32° = 90° (Right angle)
2 u = 90° - 32° = 58°
1 u = 58° ÷ 2 = 29°
∠RTU
= 29° + 32°
= 61°
Answer(s): (a) ST or TS; (b) 61°
