Answer:

Length arc AB = 3.14 in

Step-by-step explanation:

Length of arc AB = central angle/360 * 2πr

Central angle = 30°

Radius (r) = 6 in.

Substitute

Length of arc AB = 30/360 * 2*π*6

Length arc AB = 3.14 in. (Nearest tenth)

What is the value of cos(150°)?

baherus [9]

ANSWER

$-\frac{\sqrt[]{3}}{2}$

EXPLANATION

Given

$\begin{gathered} \cos \text{ 150} \\ \end{gathered}$

We can find cos 150 by using

$\begin{gathered} \cos (180-\theta)=-\cos \theta \\ \Rightarrow\cos (180-\theta) \\ =-\cos 30 \end{gathered}$

recall that

$\begin{gathered} \cos 30=\frac{\sqrt[]{3}}{2} \\ \end{gathered}$

Hence,

$\begin{gathered} \cos 150=-\cos 30 \\ =-\frac{\sqrt[]{3}}{2} \\ \end{gathered}$

Therefore, the value of cos 150 is

$-\frac{\sqrt[]{3}}{2}$
