Step-by-step explanation:
Thus, the measure of central angle is as: CA=360∘n C A = 360 ∘ n . Thus the internal angle is product of central angle and difference of sides and 2, while external angle is equal to central angle
Answer:
Step-by-step explanation:
Since the denominators are the same, we can just subtract 4 from 9 to get 5
The denominators should not be subtracted... they will remain the same
Now we take the result from 9-4 which equals 5
And we put that back into the equation so we have
This is not in simplest form. In order to get simplest form. Divide each number by two... so now we have
