Answer 2

Answer:

$\displaystyle\theta = {30}^{ \circ}$

Step-by-step explanation:

we would like to solve the following equation:

$\displaystyle\sin( \theta) = \frac{5}{10}$

notice that, the fraction can be reduced therefore reduce fraction:

$\displaystyle\sin( \theta) = \frac{ \cancel{5 \: }}{ \cancel{1 0} _{2} }$

$\displaystyle\sin( \theta) = \frac{1}{2}$

by trigonometric value table we obtain:

$\displaystyle\sin( \theta) = \sin( {30}^{ \circ} )$

get rid of sin:

$\displaystyle\theta = {30}^{ \circ}$

and we are done!
