Given that the leg opposite the 30° angle for a triangle has a length of 12, find the length of the other leg and the hypotenuse The hypotenuse is 2 × 12 =A triangle is a right triangle with angle measures of 30º, 60º, and 90º (the right angle ) Because the angles are always in that ratio, the sides are also always in the same ratio to each otherIn the study of trigonometry the 30 60 90 triangle is considered a special triangle knowing the ratio of the sides of a 30 60 90 triangle allows us to find the exact values of the three trigonometric functions sine cosine and tangent for the angles 30 and 60 Special right triangles 30 60 90 A 45 45 90 isosceles right triangle has a side 1
