Question

The side lengths of a 30-60-90 are in the ratio What is sin 60°?

Answer 1

B. √3/2

Step-by-step explanation:

We can represent the ratio 1 : √3 : 2 with the following triangle

Then, the sin 60 is the ratio of the opposite side and the hypotenuse, so

`\begin{gathered} \sin60=\frac{Opposite\text{ side}}{hypotenuse} \\ \\ \sin60=(√(3))/(2) \end{gathered}`

Therefore, the answer is B. √3/2
