Question 512025: Some facts about the maximum banking angles of Daytona International Speedway at corners 1,2,3, and 4 are below. Find angle 3. Explain your steps.
Facts:
Angle 1 + Angle 3 + Angle 4= 93
Angle 2 + Angle 4=62
Angle 2=Angle 3
Angle 1=Angle2
Please help me. I'm so confused and I don't know where to start.

Really short solution: subtract the second equation from the first.

(Angle 1 + Angle 3 + Angle 4) - (Angle 2 + Angle 4) = 93 - 62 = 31

(Angle 1 - Angle 2) + Angle 3 = 31, since Angle 1 = Angle 2, we get Angle 3 = 31. It turns out that all four angles are equal.
