The cold wind causes us to feel the air temperature cold. This is called the cooling effect of the wind. Wind with a speed of 60 km per hour causes the air temperature to feel 8 ° C cooler in Ağrı. When the air temperature in Ağrı is -3 ° C, how many degrees is the air temperature felt?

The air temperature is felt at -11 ºC.

Step-by-step explanation:

According to the statement, wind flow causes that air temperature is apparently lower than real temperature. If wind causes the air temperature to feel 8 ºC cooler in Ağrı and real temperature is -3 ºC, then the apparent temperature is:

The air temperature is felt at -11 ºC.

∠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.
