Answer 1

Answers:

10) $30\°$

11) $30\°$

12) $45\°$

Step-by-step explanation:

In this problem we have to find the angle of each expression:

10) $cos(x)=\frac{\sqrt{3}}{2}$

$x=cos^{-1}(\frac{\sqrt{3}}{2})$

$x=30\°$

11) $sin(x)=\frac{1}{2}$

$x=sin^{-1}(\frac{1}{2})$

$x=30\°$

12) $tan(x)=1$

$x=tan^{-1}(1)$

$x=45\°$
