Respuesta :
A triangle equals to 180°
40 + 30 = 70
180 - 70 = 110
The other remaining interior angles are 110°
Answer:
The interior angles are 30°, 40° and 110°
Step-by-step explanation:
One of the interior angles of a triangle is equal to 30° and one of the exterior angles is equal to 40°.
Interior angle whose exterior angle is equal to 40° = 180 - 40° = 140°
Total interior angle of triangle = 180°
Interior angle 1 + Interior angle 2 + Interior angle 3 = 180°
30° + 40° + Interior angle 3 = 180°
Interior angle 3 = 180 - 70 = 110°
The interior angles are 30°, 40° and 110°
