What is the ratio of the number of degrees in the interior angle of a regular pentagon to the number of degrees in the interior angle of a regular hexagon?
Write your answer as a common fraction.
Isn't the answer 3/4?
Since you do:
180(n-2) : 180(n-2)
so it's
540 : 720
which is 3:4
Well, that's for the SUM of the interior angles. The question is asking for the "interior angle," which is just one angle.
So you got the interior angles as 540 for a pentagon and 720 for a hexagon, right? That is correct.
Now just divide 540 by 5 because a pentagon has 5 angles to find the measure of one angle. 540 divided by 5 is 108.
Same thing - divide 720 by 6 b/c a hexagon has 6 angles. 720 divided by 6 is 120.
Now - \(108:120=9:10=\frac{9}{10}\)
You are very welcome!
