Question

if an exterior angle of a triangle is 130 degrees and one of the interior opposite angle is 60° find all other interior opposite angles

Answer 1

by linear pair

A+130 = 180

A = 50

AND GIVEN THAT

60 IS ALSO INTERIOR ANGLE

SO, A+B+C = 180

 ==> 50+60+X = 180

==> X = 180-110

==> X = 70  

Answer 2

here is your answer

exterior angle of a triangle=sum of interior opposite angles

exterior angle=130

interior opposite angle=60

let other interior opposite angle be x

then

x+60=130

x=130-60

x=70

hope it helps
