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
5 yards + 3 yards = 8 yards of fabric. The answer is A. Hope this helps.
I believe it would be 50 degrees. If the triangle has two congruent sides, then most likely the triangle's angles are all the same.
