VikaD [51]

Answer:

Option D

Step-by-step explanation:

F=\frac{9}{5}C+32\\\\F-32=\frac{9}{5}C  \\\\5(F-32)=9C\\\\\frac{5(F-32)}{9}=C  \\\\C=\frac{5}{9}( {F-32})

For F=77°F

C=\frac{5}{9}(F-32) \\\\C=\frac{5}{9}(77-32)\\\\C=\frac{5}{9}(45)\\\\C=\frac{225}{9} \\\\C=25

Find the measure of each interior angle of a regular 25 sided polygon
uranmaximum [27]
The formula for finding the total interior angle measure is:

180(n-2)

n is the number of sides.

180(25-2) = 4140

So each interior angle would be: 165.6

4140/25 = 165.6

Hope this helps :)
