RSTU is a rhombus, NPU and SPT are straight lines. If SP = PU, ∠PUT = 16° and ∠QST = 35°, find
- ∠PTU
- ∠QNP
(a)
∠PTU
= 88° - 16°
= 72° (Exterior angle of a triangle)
(b)
∠SNP
= 88° - 35°
= 53° (Exterior angle of a triangle)
∠QNP
= 180° - 53°
= 127° (Angles on a straight line)
Answer(s): (a) 72°; (b) 127°
