Question

the exterior angle of a triangle is 125° and one of its opposite angle is 40° then the other opposite interior angle is ​

Answer 1

Step-by-step explanation:

exterior angle = sum of 2 opposite interior angles

125 =40 + x

x= 85°

Answer 2

Answer:

85°

Step-by-step explanation:

suppose a triangle abc having 125° of exterior angle at point "a" so interior angle a would be

180-125 = 55

next we have another angle 40 suppose at B so C would be

A+B+C = 180

C = 180-55-40

C = 55°
