The sum of the angles in a triangle is 180°. Therefore, the sum of the angles given (30° and 70°) is 100°. To find the measure of angle x, we subtract the sum of the given angles from the total sum of angles in a triangle:
180° - 100° = 80°
Therefore, the measure of angle x is 80°.
The angles of a triangle measure 30° 70
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)
