To find the perimeter of a triangle when one side is 1, and the adjacent angles are 30 and 45 degrees, we can apply the Pythagorean theorem. First, let's draw an imaginary line from the opposite vertex to the side with length 1, creating two right triangles. By knowing the properties of angles 30 and 45 degrees, we can determine that the height of the triangle is 1/2 and √3/2 respectively. Now, we can use the Pythagorean theorem (a² + b² = c²) to find the length of the hypotenuse, which is the same as the side of the triangle with length 1. By substituting 1/2 and √3/2 respectively for a and b, we get √(1/4 + 3/4) = √1 = 1. Therefore, the perimeter of the triangle is 1 + 1 + 1 = 3.
