(for each question, enter your answer as a comma-separated list,
e. g., x1,x3,x5. enter none if no points satisfy the given condition)

no this is a nonlinear negative

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
