Question

Identify sin Y as a fraction and as a decimal rounded to the nearest hundredth. Please help!

Answer 1

Answer: Choice B

Explanation:

You divide the opposite side over the hypotenuse to compute the sine ratio of the angle. If angle Y is the reference angle, then side XZ = 7.4 is the opposite side and YZ = 10.9 is the hypotenuse (always opposite the 90 degree angle).

Therefore,

sin(Y) = opposite/hypotenuse

sin(Y) = 7.4/10.9

sin(Y) = 0.678899

sin(Y) = 0.68
