Answer:
Let the interior angle be x
Exterior angle is the sum of interior opposite angles
∴x+x=80°
⇒2x=80°
⇒x = 80° /2°
=> x = 40°
Hence, the interior angles is 40°

Answer:
40°
Step-by-step explanation:
in a triangle ABC,
let, exterior angleC= 80°
then, by the linear pair of angles,
interior angleC = 180°- exterior angleC
so, interior angleC= 180°-80°
=100°
Now, According to question, angle opposite to this angle are equal to each other, Let they are =x
