Answer:
104°, 38°, 104°, 38°
Step-by-step explanation:
∠1= ∠3 as opposite angles
and ∠2= ∠4= 38°
∠1= ∠3= 180- 2*38°=104°
Answer:
The answer to your question is 3. 0
Step-by-step explanation:
For an angle of 180°:
- hypotenuse = 1
- Adjacent side = 1
- Opposite side = 0
Then, sin Ф = 
sin 180° = 
sin 180° = 0
