B+133=180
b=47
and 80+a+b=180
80+a+47=180
a=180-127
a=53
The answer would be <span>A) rational.
The rational number is number that can be represented as a ratio of "a/b" where a and b is an integer. When you multiply two rational number of a/b and c/d, the result would be: a/b * c/d= ac/ bd
Since a and c is an integer, the product of ac would be integer too. The same thing applies to bd.
Since ac and bd is an integer, then ac/bd would be a rational number</span>
