In the figure, MFHL and MFGK are parallelograms. Given that ∠HFJ = 13°, ∠MLK = 67° and MKL is an isosceles triangle where MK = ML. Find
- ∠FJH
- ∠MFJ
(a)
∠FHL
= 180° - 67°
= 113° (Interior angles)
∠FJH
= 180° - 113° - 13°
= 54° (Angles sum of triangle)
(b)
∠MFJ
= ∠FJH
= 54° (Alternate angles)
Answer(s): (a) 54°; (b) 54°
