NPQR is a rhombus, KLR and PLQ are straight lines. If PL = LR, ∠LRQ = 19° and ∠MPQ = 31°, find
- ∠LQR
- ∠MKL
(a)
∠LQR
= 84° - 19°
= 65° (Exterior angle of a triangle)
(b)
∠PKL
= 84° - 31°
= 53° (Exterior angle of a triangle)
∠MKL
= 180° - 53°
= 127° (Angles on a straight line)
Answer(s): (a) 65°; (b) 127°
