Answer:
see explanation
Explanation:
∠3 = 38° ( alternate to ∠BGA )
∠4 = ∠3 = 38° ( congruent angles )
∠BCF = 180° - (38 + 32)° ← sum of angles in a triangle )
= 180° - 70° = 110°, thus
∠5 = 110° ( vertical to ∠BCF
∠6 = ∠7 ( base angles of isosceles ΔCDE ), thus
∠6 = ∠7 = 0.5(180 - 110)° = 0.5 × 70 = 35°
∠8 = 90° ( marked right angle )
Thus ∠4 = 38°, ∠5 = 110°, ∠6 = ∠7 = 35° and ∠8 = 90°
