Given:
In ΔWXY, x = 680 inches, w = 900 inches and ∠W=157°.
To find:
The all possible values of ∠X, to the nearest degree.
Solution:
Law of Sines:

For ΔWXY,

Now,








Therefore, the value of ∠X is 17 degrees.
The answer would be A. There is a phase shift to the left. Because you are adding pi/6.
Answer:4/6
Step-by-step explanation:because we multiply the fraccion by 2
