I took a different practice test elsewhere that had a similar question with the same answers. On that test, it asked about pi/3 radians, or 60°, so +4.3v is probably what they wanted and simply mistyped the question.
That test had 100 questions and I was doing great until it started asking me aviation questions. Knowing nothing about aviation, which is about 30% of the test, I got 67% out of the required 75%. All I gotta do is brush up on aviation tech and I'll have it whooped!
