Given that DEFG is a rhombus, calculate
- ∠l
- ∠n
(a)
∠DHG = ∠EHK = 102° (Vertically opposite angles)
∠l
= 180° - 102° - 25°
= 53° (Angles sum of triangle)
(b)
∠GFE
= 180° - 25° - 25°
= 130° (Angles sum of triangle)
∠n
= 360° - 102° - 130° - 25°
= 103° (Sum of Angles in a quadrilateral)
Answer(s): (a) 53°; (b) 103°
