Statement Reason
1. m∠AOC+m∠______ = ______ 1. _____________
2. m∠______ + ______ +m∠BOC=90° 2. Substitution
3. m∠BOC = _________ 3. Algebra
4. m∠AOC = _________ 4. Algebra

Answer 1

Statement Reason

1. m∠AOC+m∠COB= 90° 1. complementary angles

2. m∠30° + BOC+m∠BOC=90° 2. Substitution

3. m∠BOC = 30° 3. Algebra

4. m∠AOC = 60° 4. Algebra
