Today I present the answer to yesterday’s Mathematics Knowledge question. An acute angle is less than 90 degrees. As an ASVAB tutor, I remind the students in my ASVAB prep course of the importance of knowing the measurement of different angles. Knowing angle measures for geometry in the Mathematics Knowledge section of the ASVAB will help to improve the math score. Brushing up on algebra and geometry is an essential part of improving the Mathematics Knowledge score.
