Math Help!!! Can someone help me please?

A triangle has angle measures of 115°, 40°, and 25°.
Explain how to find the measures of the triangle’s exterior angles.

Answer 1

The interior angles added with the corrrsponding exterior angle will equal 180 because there linear so just subtract 180 from the interior angle

180-115=65
180-40=140
180-25=155

you can check by adding up all the angle measures and seeing if it equals 360

(exterior angle of a triangle added equal 360 while interior angles added up equal 180)
