Which two statements describe the ocean floor A. there are underwater mountain chains
B. there are many active undersea volcanoes
C. it has only smooth surfaces between continental shelves
D. it is covered with underwater forest of tall trees

I believe the answer is B.

Step-by-step explanation:

If you think about it, none of the other answers really make sense. This is the only one that I can see that actually makes sense. If I am wrong, I am very sorry.

2. 365/5=

73*2   = 146

∠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.
