PQRS is a rhombus, LMS and QMR are straight lines. If QM = MS, ∠MSR = 17° and ∠NQR = 26°, find
- ∠MRS
- ∠NLM
(a)
∠MRS
= 82° - 17°
= 65° (Exterior angle of a triangle)
(b)
∠QLM
= 82° - 26°
= 56° (Exterior angle of a triangle)
∠NLM
= 180° - 56°
= 124° (Angles on a straight line)
Answer(s): (a) 65°; (b) 124°
