Please help ASAP! Law of sines...

kirza4 [7]

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
