Yesterday I posted a Mathematics Knowledge problem that could appear on the ASVAB. I cover the topic of angles in my ASVAB prep course. When I tutor my students for the ASVAB, I remind them to know the key math vocabulary that is essential to pass the test. Knowing the necessary vocabulary, formulas, and conversions will help to improve your ASVAB math score. This question asked about complementary angles. Complementary angles add up to 90 degrees. If an angle is 40 degrees, the complementary angle is 90 – 40 = 50 degrees. Did you know how to solve this one?
