LMNP is a rhombus, HJP and MJN are straight lines. If MJ = JP, ∠JPN = 19° and ∠KMN = 26°, find
- ∠JNP
- ∠KHJ
(a)
∠JNP
= 85° - 19°
= 66° (Exterior angle of a triangle)
(b)
∠MHJ
= 85° - 26°
= 59° (Exterior angle of a triangle)
∠KHJ
= 180° - 59°
= 121° (Angles on a straight line)
Answer(s): (a) 66°; (b) 121°
