B 110 degrees C 70 degrees D 110 degrees
A pair of supplementary angles add up to 180 degrees. In this instance, the supplement of an angle of 70 degrees is 180 - 70 = 110 degrees.
Supplementary angles add up to 180° Let the smaller angle be x, then the larger angle is x + 70°, and: x + (x + 70°) = 180° → 2x + 70° = 180° → 2x = 110° → x = 55° → x + 70° = 55° + 70° = 125° Thus the two angles are 55° and 125°. Therefore the angle you want is the larger at 125°.
70 degrees
110 degrees creates an obtuse angle.
