Points A, B, and form a triangle. Complete the statements to prove that the sum of the Interior angles of ABC nec in
Statement
Reason
Points A, B, and C form a triangle.
given
Let DE be a line passing through B and parallel to AC. definition of parallel lines
23 25 and 21 - 24
m21 = m 24 and 23 = m25
m24+ m2 2 + m 25 = 180°
angle addition and definition of a straight line
m21 + m2 2 + m23 = 180°

Explain how you do each step what term makes it inconsistent y=2x - 4 ?

Which shows the correct lengths of side c in both scales? scale 1: 45 m; scale 2: 60 m scale 1: 60 m; scale 2: 45 m scale 1: 36 m; scale 2: 27 m scale 1: 27 m; scale 2: 36 m mark this and return save and exit

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
