Question

The exterior angle of a triangle is 164 degree and one
 of its interior opposite angle is 98 degree. Find the other
 interior opposite angle. ​

Answer 1

Answer:

• Let the other interior angle be x

${ \rm{x + 98 \degree = 164\degree}} \\ \\ { \rm{x = 164\degree - 98\degree}} \\ \\ { \boxed{ \rm{x = 66\degree}}}$
