One of two complementary angles is 4 degrees more than the other. Find the angles. (Recall that complementary angles are angles whose sum is 90 degrees.) Which of the following equations can not be used to solve the problem if x represents one of the angles?
A. 2x - 4 = 90
B. 2x + 4 = 90
C. x + 4 = 90
complimentary angles add up 90° let one of the angles be x, the 2nd angle will be (x+4) thus the total sum will be: x+(x+4)=90 2x+4=90 thus the right equation is: B. 2x + 4 = 90
