It will even tell you if more than 1 triangle can be created. Unique 30 60 90 Triangle Sides Stickers designed and sold by artists. And because this is a 30-60-90 triangle, and we were told that the shortest side is 8, the hypotenuse must be 16 and the missing side must be $8 * √3$, or $8√3$. If you only know the hypotenuse (figure 9), multiply this by the reciprocal of the square root of 2 (about .707) to calculate the length of the leg. A 30-60-90 triangle is a special right triangle (a right triangle being any triangle that contains a 90 degree angle) that always has degree angles of 30 degrees, 60 degrees, and 90 degrees. Now we know that: a = 6.222 in; c = 10.941 in; α = 34.66° β = 55.34° Now, let's check how does finding angles of a right triangle work: Refresh the calculator. Here, we are given side b, side a and its opposing angle A. Do not use a trig tool or a calculator.
