Angles A and B are supplementary angles. The mZA = (9x - 12) and the mZB = (24x + 60).

/ A = 24°

/ B = 156°

Step-by-step explanation:

Supplementary angles add up to 180°.

Therefore, / A + / B = 180

(9x - 12) + (24x + 60) = 180

9x - 12 + 24x + 60 = 180

33x + 48 = 180

33x = 180 - 48

33x = 132

x = 132/33

x = 12/3

x = 4

/ A = (9x - 12)

= (9(4) - 12)

= (36 - 12)

= 24°

/ B = (24x + 60)

= (24(4) + 60)

= (96 + 60)

= 156°

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
