I thought this might be easier to answer and show the work using a pic
From the equilateral (60-60-60) triangle with all legs of length 1, we can view half the triangle, forming a 30-60-90 triangle, with the hypotenuse measuring 1, the short leg1/2<span>, and the long leg 3 2. Therefore, we have sin 30° = </span>1/2<span>, cos 30° = 3 2, sin 60° = 3 2 and cos 60° = </span>1/2<span>.
i hope this help</span>
