To determine the temperature in Fahrenheit, multiply the Celsius temperature by 1.8 then add 32. Determine the Celsius temperature if it is 89°F outside. Round your answer to the nearest hundredth.

86 degrees F

Step-by-step explanation: To convert from Fahrenheit to Celsius, use this equation:

C = (F-32) x 5/9 ...or... C = (F-32)/1.8

To convert from Celsius to Fahrenheit, use this equation:

F = (C x 9/5) + 32 ...or... F = (C x 1.8) + 32

3. Using Your Head (deg. C to deg. F only)...

Here's a trick for converting Celsius to Fahrenheit in your head:

1) double the Celsius temperature

2) subtract one tenth of this value from itself

3) add 32

let's use 30 degrees C as an example.

1) double the Celsius temperature (2 x 30 = 60)

2) subtract one tenth of this value (60 - 6 = 54)

3) add 32 (54 + 32 = 86 degrees F)

step-by-step explanation:

∠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.
