Question

Find the length of side x in simplest radical form with a rational denominator.30°х60°12

Answer 1

Ok, to find the lenght of side x we are going to use the sine function:

$\sin (30)=\frac{12}{x}$

Clearing x:

$x=\frac{12}{\sin (30)}=\frac{12}{1/2}=24$

Finally we get that x is equal to 24.
