The graph below shows the height of a hot air balloon during a trip. What are the variables? Describe how they are related at various points on the graph.
Height (leet)
Time (hours)
o
A The variables are height and time. The balloon rises quickly to a certain height, levels off for a while, then gradually returns to the
ground.
B. The variables are height and time. The balloon gradually rises to a certain height, levels off for a while, then quickly returns to the
ground.
OC. The variables are hours and feet. The balloon rises quickly to a certain height, levels off for a while, then gradually returns to the
ground
D. The variables are hours and feet. The balloon gradually rises to a certain height, levels off for a while, then quickly returns to the
ground

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.
