Complete the two column proof. given 2=4 m<2=110 prove m<3=70

Answer 1

Statements Reasons
1. 2 = 4 Given
2. m∠2 = 110 Given
3. ∠2 and ∠3 are supplementary Definition of supplementary angles
4. m∠2 + m∠3 = 180 Sum of angles in a straight line is 180 degrees
5. m∠3 + m∠2 = 180 Commutative property of addition
6. m∠3 + 110 = 180 Substitution (from statement 2)
7. m∠3 = 180 - 110 Subtraction property of equality
8. m∠3 = 70 Simplification
