Answer:
20
Step-by-step explanation:
Let the number of sides be n
One exterior angle = 360/n
Exterior angle + interior angle = 180
Interior angle = 180 - Exterior angle
= 180 - 360/n
Sum of interior angle = n(180 - 360/n) = 3240
n(180 - 360/n) = 3240
180n - 360 = 3240
180n = 3240 - 360
= 3600
n = 3600/180
= 20
Huh? Theres no picture or anything..? Care to explain?
Step-by-step explanation:
measure all the sides then multiply you will get the answer

There are two extra credit questions on the Biology test, and 27 questions overall [including the afore-mentioned two]. If Jo answers all questions [including the extra credits] correctly, and each is worth the same amount, what score does she earn?
Answer: 108%
27 − 2 = 25. 100 / 25 = 4. So, each question is worth 4%. 2 x 4% = 8% That’s how much the extra credit is worth. 100% (main test) + 8% (extra credit) = 108% (best score possible).
