Question 1008320

The ratio of the lengths of the sides of a right triangle is {{{ 1:sqrt (3) :2 }}} . What is the sine of the triangle's smallest angle? Show all steps.
<pre>Side ratio-values of: {{{1:sqrt (3):2}}} are consistent with a 30-60-90 special right triangle. In this case, smallest angle is {{{30^o}}}, and the sine of {{{30^o}}} is {{{highlight_green(1/2)}}}. 
Verify using the unit circle, or you may know that upon studying trig ratios.
