Answer:

b = 35.00

Step-by-step explanation:

To make use of the Law of Sines, you need to know angle B. Of course, its value will make the sum of all angles be 180°, so it is ...

B = 180° -34.5° -29.8° = 115.7°

Then the law of sines tells you ...

b = sin(B)·a/sin(A) = 22·sin(115.7°)/sin(34.5°)

b = 35.00

Answer:

Above the dashed line

Step-by-step explanation:

That y is greater than the values on the line tells you that the shading is above the line.

That the "equal to" case is not included tells you that the line is dashed.
