If a piece of flat stock needs to be bent to a closed angle of 15°, through what angle must it be bent?

  1. 15°

  2. 45°

  3. 165°

  4. 180°

The correct answer is: 165°

A This option is incorrect because a piece of flat stock needs to be bent to a closed angle of 15°, not bent by that angle itself. B: This option is incorrect because it is the complementary angle to 15°, meaning it is the angle that when added to 15°, results in a total of 90°, not the closed angle itself. D: This option is incorrect because a closed angle of 15° means that the angle is not fully opened and therefore not a full 180°. The correct angle must be smaller than 180°. By process of elimination, the only possible correct choice is C, as it is the only angle that is larger than 15° and smaller than 180°, which is necessary for a closed angle of 15°.
