ZA, 2B, 2C are the interior angles of AB
mZABC + mZBAC + m ZACB​

Answer 1

Answer:

theorem, The sum of the measures of the interior angles of a triangle equals 180º. ... 2. The angles in a triangle are represented by (4x - 6)º, (2x + 1)º and (x + 3)º. Is this a right triangle ... m∠A'BB''. • By substitution, m∠ABC + m∠ACB + m∠BAC = 180. ... through C to E, and draw an auxiliary line through C parallel to AB . 2
