## Elementary Geometry for College Students (6th Edition)

$sin(s)= \frac{1}{2}$
We know that for a 30 60 90 triangle, the ratio of the lengths of the sides is 1:2: $\sqrt{3}$. We know that the $\sqrt{3}$ side is adjacent to the 30 degree angle, so: $sin(s)= \frac{o}{h}$ $sin(s)= \frac{1}{2}$ To draw this, use a protractor to create a right triangle with angles of 30, 60, and 90 degrees.
