The basic 30-60-90 triangle ratio is: Side opposite the 30 angle: x. The length of leg a is 1.5748 runs between the 90 deg and 40 deg angles and is opposite angle a. Also, the unusual property of this 30 60 90 triangle is that it's the only right triangle with angles in an arithmetic progression. The sides of a right triangle are commonly referred to with the variables a, b, and c, where c is the hypotenuse and a and b are the lengths of the shorter sides. In this type of right triangle, the sides corresponding to the angles 30-60-90 follow a ratio of 1:3:2. R = radius of circumscribed circle. [1], sin(A) < a/c, there are two possible triangles, solve for the 2 possible values of the 3rd side b = c*cos(A) [ a2 - c2 sin2 (A) ][1], for each set of solutions, use The Law of Cosines to solve for each of the other two angles, sin(A) = a/c, there is one possible triangle, use The Law of Sines to solve for an angle, C, use the Sum of Angles Rule to find the other angle, B, use The Law of Sines to solve for the last side, b, sin(A) > a/c, there are no possible triangles. So we use the general triangle area formula (A = base height/2) and substitute a and b for base and height. However, the methods described above are more useful as they need to have only one side of the 30 60 90 triangle given.
