Mathematics Knowledge

As an ASVAB tutor, I focus very heavily on the math sections of the ASVAB.  The two math sections of the ASVAB are Arithmetic Reasoning and Mathematics Knowledge.  Yesterday I presented a question on Mathematics Knowledge.  It was a geometry question.  The question asks about complementary angles.  Do you know what complementary angles are?

If 2 angle are complementary, and one of the angles measures 40 degrees, what is the measure of the other angle?

  1. 50
  2. 90
  3. 140
  4. 180

Complementary angles are angles that add up to 90 degrees.  To answer yesterday’s question, if 2 angles are complementary and one measures 40 degrees, subtract 40 degrees from 90 degrees to find the answer.

90 – 40 = 50 degrees.

Did you know how to answer this question?
