Math Knowledge

In working as an ASVAB tutor, I spend most of my class time explaining either Arithmetic Reasoning or Mathematics Knowledge.

Today I present a question on Mathematics Knowledge.  It is a geometry question.  One of the 15 subtopics I cover in Mathematics Knowledge is angles and slope.  I remind my students of the importance of knowing the different types of angles including complementary, supplementary, acute, right, obtuse, and so on.

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

I will present the answer to this question tomorrow.
