Answer:
The answer should be 34!!
Step-by-step explanation:
Answer:
∠ 3 = 40°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles in Δ ABC for ∠ 1
∠ 1 = 180° - (58 + 90)° = 180° - 148° = 32°
∠ 2 = ∠ 1 = 32° ( vertical angles )
Thus
∠ 3 = 180° - (108 + 32)° = 180° - 140° = 40°
