Given: exterior angle of a triangle is 125° and one of the opposite interior angle is 45°.

To find: another interior angle of triangle .

Solution: we know that exterior angle is equal to sum of two opposite interior angle of a triangle .

x=125°-45°

=80°

Hence, another interior angle of a triangle is
