Answer

$sin(s)=\sqrt3 /2$

Work Step by Step

We know that for a 30 60 90 triangle, the ratio of the lengths of the sides is 1:2: √3. We know that the √3 side is opposite the 60 degree angle, so: $sin(T)=\frac{o}{h}$ $sin(s)=\sqrt3 /2$ To draw this, use a protractor to create a right triangle with angles of 30, 60, and 90 degrees.
