Consider the following completed two-column proof (the diagram "at the left" is not needed; note the four given facts below): AUTO RACING The Talladega Superspeedway racetrack in Alabama has four banked turns, which are described in the diagram at the left. Use the given information about the maximum banking angle of the four turns to find m2 4. SOLUTION m2 1 + m2 2 = 66° m/1+ m2 + m2 3 99⁰ 66° + m3 = 99⁹ m/3=33° m23=m21, m1 = m24 Given m/3= m2 4 m24 = 33° Given Given m/1m2 = 66° m21+ m2 2 + m23 = 99⁰ m/3= m/1 m21=m24 Substitution property of equality Subtraction property of equality Transitive property of equality Substitution property of equality In the above, m4 for example, means the "measurement of angle 4." It's another way of just stating 24. The third step in the proof is true because (select all that apply)​
