The angles of a triangle measure 30°, 70°, and x. The Triangle Angle Sum Theorem states that the sum of the angles inside a triangle must equal 180°. Based on this theorem, what is the measure of angle x?(1 point) Responses 100° 100° 80° 80° 280° 280° 110°
The sum of the angles inside a triangle must equal 180°. So, the measure of angle x can be calculated as follows:
30° + 70° + x = 180°
100° + x = 180°
x = 180° - 100°
x = 80°
Therefore, the measure of angle x is 80°.
Correct answer: 80°
