Angle a and angle b are complementary angles. if m< a = x, which expression represents the number of degrees in angle b?
(1) x - 180
(2) x - 90
(3) 180 - x
(4) 90 -x

Complimentary just means that they add to be 90, so you take 90 degrees and subtract the angle you already have in order to get the complementary angle

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
