PLS HELP MEEMEE In June, the average temperature at the North Pole is 59° F. In December, the average temperature at the North Pole is 69° F colder than June's average temperature. In February, the average temperature at the North Pole is ½ as cold December's average temperature.

What is the average temperature, in degrees Fahrenheit, at the North Pole in Febru

I WILL MARK BRAINLIST IF WORK IS SHOWEN

59-69=-10,     1/2 of 10=5

so the answer is 5 degrees Fahrenheit

Step-by-step explanation:

The 59-69 came from December being 69 degrees less than junes temperature, and the 1/2 of 10 came from February being half as cold as December's temperature.

Hope this helped!

February's Average Temperature 5º

Step-by-step explanation:

December Temp is 69º colder than June so add June's Temp and December's together 69º - 59º  = 10º

December's Temperature is 10º so if February is ½ as cold then we mutiply ½ by 10º which is 5º.  (You could also divide 10 by 2)

Frebruary's Temp is 5º

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

∠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.
