A clock shows a time of 3:20.what type of angle is this

fredd [130]

Hour hand: $\frac{35\pi}{18}$

Minute hand: $\frac{11\pi}{6}*\frac{3}{3}=\frac{33\pi}{18}$

$\frac{35\pi}{18}-\frac{33\pi}{18}\\\frac{2\pi}{18}\\\frac{\pi}{9}$

Acute angle

Right angle $=\frac{\pi}{2}$
Obtuse angle $>\frac{\pi}{2}$
Straight angle $=\pi$

$0$

Acute angle.

Determine weather the statement is true or false. Justify your answer

topjm [15]

$\begin{gathered} \cos (-\frac{7\pi}{2})=\cos (\pi+\frac{\pi}{2}) \\ \cos (-\frac{7\pi}{2})=\cos (\frac{3\pi}{2}) \end{gathered}$

As we know:

$\begin{gathered} \cos (x)=0 \\ for \\ x=\pi n-\frac{\pi}{2} \\ n\in Z \end{gathered}$

For:

$\begin{gathered} n=2 \\ x=2\pi-\frac{\pi}{2}=\frac{3\pi}{2} \\ for \\ n=-3 \\ x=-3\pi-\frac{\pi}{2}=-\frac{7\pi}{2} \end{gathered}$

Therefore:

$\begin{gathered} \cos (-\frac{7\pi}{2})=0 \\ and \\ \cos (\frac{3\pi}{2})=0 \\ so\colon \\ 0=0 \\ This_{\text{ }}is_{\text{ }}true \end{gathered}$

Therefore, the statement is true
