Two angles of a triangle have measures of 55° and 65°.
Which could not be a measure of an exterior angle of the

The third angle is 180-55-65 = 60°.

Exterior angles are 180-55 = 125°, 135°, 120°

The sum of an interior angle and an exterior angle is 180°. Then the 130° is not an exterior angle of the triangle.

What is the triangle?

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

The two angles of a triangle have measures of 55° and 65°. Then the third angle (x) will be

w + 55° + 65° = 180°

                  w = 180° - 120°

                  w = 60°

Let the exterior angle be x, y, and z.

The sum of an interior angle and an exterior angle is 180°. Then we have

[tex]\rm x = 180^o - 55^o = 125^o \\\\y = 180^o - 65^o = 115^o \\\\z = 180^o - 60^o = 120^o[/tex]
