The measure of an exterior angle of a triangle is 40°. What is the sum of the measures of the corresponding remote interior angles?​

Respuesta :

Answer:

40 degrees

Step-by-step explanation:

Because there are 180 interior angles in a triangle, you need one of the sides. If an angle's exterior is 40 degrees, we know that the interior angle is 140 degrees. This means that the sum of the other interior angles have to be 40 as 180-140 is 40.

Answer:

the answer for this question is 20°
