In the figure, HJM and LJK are right-angled triangles. MJ is parallel to LK. Find
- ∠JKL
- ∠JML
(a)
∠LJM
= 360° - 90° - 90° - 121°
= 59° (Angles at a point)
∠JLK = ∠LJM = 59° (Alternate angles)
∠JKL
= 180° - ∠LJK - ∠JLK
= 180° - 90° - 59°
= 31° (Angles sum of triangle)
(b)
∠JML
= 180° - ∠LJM - ∠JLM
= 180° - 59° - 83°
= 38° (Angles sum of triangle)
Answer(s): (a) 31°; (b) 38°
