Lets draw our triangle:

Lets use the "Law of Sines" to find our side r:

\frac{p}{\sin P}=\frac{r}{\sin R}\rightarrow\frac{9}{\frac{1}{3}}=\frac{r}{\frac{2}{3}}\rightarrow9\times\frac{3}{1}\times\frac{2}{3}=r\rightarrow r=18

So r=18

Evaluate sin^-1 1/2 . Round your answer to the nearest hundredth.
adoni [48]

Answer:

<h2>30.00</h2>

Step-by-step explanation:

Given the expression sin^{-1} 1/2, the following steps must be taken to evaluate the expression.

Let\  y = sin^{-1}1/2

y = sin^{-1} 0.5

From the calculator, the value of y wil give;

y = 30\\\\y = 30.00 (to\ the \ nearest \ hundredth)

Hence sin^{-1}  0.5 = 30.00.
