what is the value of x?
º
a triangle with base on an extended line. two angle measures are given. top interior angle is twenty-eight degrees. lower left exterior angle is seventy-one degrees. lower right interior angle is labeled x degrees.

The correct answer for the question that is being presented above is this one: "The lower right interior angle is 43°"

Interior angle of a triangle and its corresponding exterior angle must have a sum of 180° when its line is extended.

Top interior angle is 28°
Lower left exterior angle is 71°
Lower right interior angle is x°

Get the left interior angle. 
Exterior angle + Interior angle = 180°
71° + Interior angle = 180°
Interior Angle = 180° - 71°
Interior Angle = 109°

Top Interior angle + Left Interior Angle + Right Interior angle = 180°
28° + 109° + x° = 180°
x = 180° - 28° - 109°
x = 180° - 137°
x = 43°

The lower right interior angle is 43°

The answer is the first one
