Use the law of wines to find the value of y. Round to the nearest Tenth
Eva8 [605]

Answer:

y ≈ 2.5

Step-by-step explanation:

Using the Sine rule in Δ XYZ

\frac{sinZ}{XY} = \frac{sinY}{XZ} , substitute values

\frac{sin50}{2} = \frac{sin75}{y} ( cross- multiply )

y sin50° = 2 sin75° ( divide both sides by sin50° )

y = \frac{2sin75}{sin50} ≈ 2.5 ( to the nearest tenth )

WINSTONCH [101]
Since Peyton has 2 pizzas and each is cut into 10 equal slices that would mean 2x10 which is 20 and then it says she and her friends eat 14 slices which means take away 14 minus 20 which is 6 so the decimal for only 6 would be 0.6 which is the answer. Hope this helped.
