\(a,\text{Slt: }\widehat{A_4}\text{ và }\widehat{B_1}\\ \text{Đv: }\widehat{A_4}\text{ và }\widehat{B_3}\\ b,a\text{//}b\Rightarrow\left\{{}\begin{matrix}\widehat{A_4}=\widehat{B_1}=42^0\left(\text{so le trong}\right)\\\widehat{B_2}=180^0-\widehat{A_4}=138^0\left(\text{trong cùng phía}\right)\end{matrix}\right.\)

\(\left|-\dfrac{2016}{2017}\right|=\dfrac{2016}{2017}\)

=\(\dfrac{2016}{2017}\)
