RSTU is a rhombus, NPU and SPT are straight lines. If SP = PU, ∠PUT = 16° and ∠QST = 34°, find
- ∠PTU
- ∠QNP
(a)
∠PTU
= 83° - 16°
= 67° (Exterior angle of a triangle)
(b)
∠SNP
= 83° - 34°
= 49° (Exterior angle of a triangle)
∠QNP
= 180° - 49°
= 131° (Angles on a straight line)
Answer(s): (a) 67°; (b) 131°
