NPQR is a rhombus, KLR and PLQ are straight lines. If PL = LR, ∠LRQ = 15° and ∠MPQ = 33°, find
- ∠LQR
- ∠MKL
(a)
∠LQR
= 81° - 15°
= 66° (Exterior angle of a triangle)
(b)
∠PKL
= 81° - 33°
= 48° (Exterior angle of a triangle)
∠MKL
= 180° - 48°
= 132° (Angles on a straight line)
Answer(s): (a) 66°; (b) 132°
