If A and B are the angles, then A + B = 180 and A - B = 20 So that 2A = 200 ie A = 100 and then B = 80 So the two angles are 100 and 80 degrees.
Pairs of Angles 1.Complementary Angles -are two angles together complete a right angle. *The two angles need not be to be adjacent. -to find the complement angle subtract the given angle from 90°. Ex: Give the complement of 65°. 1. 90°-65° =25° (25+ 65=90) 2. 90°-70° =20° (20+ 70=90) 2.Supplementary Angles -are two angles whose measurements are equal to 180°. *The angles not also be adjacent. -To find the supplement angle, subtract the given angle from 180°. Ex: 1. Give the supplement of 130°. 180°-130°=50° 3.Adjacent Angles -two angles with a common side and the same vertex. 4.Vertical angles -are opposite angles formed two intersecting lines. They have a common vertex but no common side.
160 The 2 angles must equal 180 degrees, so 160 is the answer.
20....or maybe 18
The percentage of 20 out of 110 is approximately 18.18%.
20 degrees
Its supplementary angle is 160 degrees because supplementary angles add up to 180 degrees

20 degrees. the definition of a supplementary angle is two angles that add up to 180 degrees.
20 degrees
A pair of supplementary angles add up to 180 degrees. Therefore, the supplement to a 20 degree angle is equal to 180 - 20 = 160 degrees.
160 The 2 angles must equal 180 degrees, so 160 is the answer.
Correct. Congruency means that two triangles have three pairs of congruent angles and corresponding sides of the same lengths. A pair of triangles with three pairs of congruent angles but sides of different lengths are similar, not congruent.
