The question states that AB = BC, which means that triangle ABC is isosceles, and that triangle ABC is the combining of two right triangles, each with a hypotenuse of 10 and legs of 5 and 10/2 = 5. So, triangle ABD is an isosceles right triangle with interior angles of 45-45-90, which means that angle BAC is equal to 45° and x = 45. Triangle EFG is isosceles, which means that triangle EFG is the combining of two right triangles, each with a hypotenuse of 12 and one leg equal to 6. So, triangle EFH is a 30-60-90 triangle, and the leg opposite the 30° angle is equal to one half the hypotenuse, which means that angle FEH is 30° and y = 30. The correct answer is (A).
