PQRS is a rhombus, LMS and QMR are straight lines. If QM = MS, ∠MSR = 15° and ∠NQR = 26°, find
- ∠MRS
- ∠NLM
(a)
∠MRS
= 88° - 15°
= 73° (Exterior angle of a triangle)
(b)
∠QLM
= 88° - 26°
= 62° (Exterior angle of a triangle)
∠NLM
= 180° - 62°
= 118° (Angles on a straight line)
Answer(s): (a) 73°; (b) 118°
