Answer 1

Answer:

55°

Step-by-step explanation:

As we know that in a triangle, the exterior angle is equal to the sum of opposite interior angles.

So,

According to the question,

80°=25°+interior angle

interior angle =80°-25°

=55°

interior angle =55°

Hence the other interior angle is 55°

Answer 2

Answer:

25+x=80

x=80-25=55
