[/INST] To solve this problem, we can use the properties of a semicircle. The semicircle is divided into two right triangles by the diameter. The diameter is the radius of the semicircle, so it is 0. Let's call the angle we are trying to find \(\alpha\). We know that the sum of the angles in a semicircle is 180 degrees. Therefore, the sum of the angles in the two triangles is 180 degrees. Since the diameter is the radius of the semicircle, the radius of the semicircle is also 0. Therefore, the radius of each triangle is 0/2 = 0. We can use the Pythagorean theorem to find the length of the radius of the semicircle. The radius of the semicircle is the hypotenuse of the right triangle, and the diameter is one leg of the right triangle. Therefore, the radius of the semicircle is the square root of the diameter squared plus the radius squared. The diameter is given as 67, so the radius of the semicircle is the square root of 67^2 + 0^2 = 67. Now, we can use the fact that the diameter is the radius of the semicircle to find the length of the radius of the semicircle. The radius of the semicircle is 67, so the radius of each triangle is 33.5. We can use the fact that the diameter is the radius of the semicircle to find the length of the radius of the semicircle.
