T = (47-19)/4
T = 28/4
T = 7
I think that solution is what your teacher is asking for, i'm not certain but ik the answer should be 7 hours.

Answer:
BC = 6
Step-by-step explanation:
Using the sine ratio in the right triangle and exact value
sin30° = 
sin30° = 
= 
= 
= ( cross- multiply )
2x = 12 ( divide both sides by 2 )
x = 6
That is BC = 6
35, because two negatives when multiplied is equal to a positive
