Answer:
The correct options are;
1. Definition of supplementary angles
2. m∠1 + m∠2 = m∠1 + m∠3
3. m∠2 = m∠3
4. Definition of Congruent Angles
Step-by-step explanation:
The two column proof is presented as follows;
Statement 
Reason
1. ∠1 and ∠2 are supplementary Given
∠1 and ∠3 are supplementary
2. m∠1 + m∠2 = 180° Definition of supplementary angles
m∠1 + m∠3 = 180°
3. m∠1 + m∠2 = m∠1 + m∠3 Transitive Property
4. m∠2 = m∠3 Subtraction Property of Equality
5. ∠2 ≅ ∠3 Definition of Congruent Angles
Given that angles ∠1 and ∠2 are supplementary angles and angles ∠1 and ∠3 are are also supplementary angles, then the sums of m∠1 + m∠2 and m∠1 + m∠3 are equal, therefore, ∠2 and ∠3 have equal quantitative value and therefore ∠2 = ∠3 and by definition, ∠2 ≅ ∠3.

Step-by-step explanation:
Answer:
Simpson
Step-by-step explanation:
Answer:
Brian's average speed: 14.73 mile/hour
The traveled distance by skiing he estimated: 11.0475 miles.
As the information provided in table, the time he spent for skiing is 0.75
=> The distance Brian traveled by skiing: 14.73 x 0.75 = 11.0475 (miles)
=> Brian's product is correct.
=> Rounding to the nearest whole number => 11.0475 = 11 (miles)
Rounding the Brian's average speed to the nearest whole number:
=> 14.73 = 15 mile/hour
Round the activity time to the nearest whole number:
=> T = 3 + 1.45 + 1.2 + 0.75 = 6.4 = 6 (hour)
Hope this helps!
