Please help me :( [ill give :D]

See below

Step-by-step explanation:

For both problems, we can use a proportion to solve.

1.

              [cross multiply]

672=4x                         [divide both sides by 4]

x=168

It would take 168 minutes or 2 hours and 48 minutes.

2.

               [cross multiply]

56x=168                       [divide both sides by 56]

x=3

Liam would be able to fit 3 tyres.

∠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.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
