RSTU is a rhombus, NPU and SPT are straight lines. If SP = PU, ∠PUT = 20° and ∠QST = 35°, find
- ∠PTU
- ∠QNP
(a)
∠PTU
= 82° - 20°
= 62° (Exterior angle of a triangle)
(b)
∠SNP
= 82° - 35°
= 47° (Exterior angle of a triangle)
∠QNP
= 180° - 47°
= 133° (Angles on a straight line)
Answer(s): (a) 62°; (b) 133°
