Answer:
68°
Step-by-step explanation:
since the angle given is a complementary angle, we know that the sum of it must equal 180°
let the unknown angle below j be x so,
[tex]25+43+x=180\\x=180-25-43\\x=112[/tex]
now since the angle on the left of j is equal to x we can say
[tex]x+j=180\\j=180-x\\j=180-112\\j=68[/tex]
