5) Notice that angles 4 and 2 are corresponding angles, since FG is parallel to HJ then:
[tex]m\angle4=m\angle2.[/tex]
If m<2=45º, then by the transitive property we get:
[tex]m\angle4=45º.[/tex]
7) Notice that angles 3 and 6 are aternating exterior angles, since FG is parallel to HJ then:
[tex]m\angle3=m\angle6.[/tex]
If m<6=135º then by the transitive property we get:
[tex]m\angle3=135º.[/tex]
Answer:
(5)
[tex]m\angle4=45º.[/tex]
(7)
[tex]m\angle3=135º.[/tex]
