<u>Given</u><u> </u><u>Information</u><u> </u><u>:</u><u>-</u>
⠀
- Each exterior angle of a regular polygon has a measure of 40°
⠀
<u>To</u><u> </u><u>Find</u><u> </u><u>:</u><u>-</u>
⠀
- The number of sides of the polygon
⠀
<u>Formula</u><u> </u><u>Used</u><u> </u><u>:</u><u>-</u>
⠀

⠀
<u>Solution</u><u> </u><u>:</u><u>-</u>
⠀
Using the formula,
⠀

⠀
Thus, the polygon is a nonagon, and hence has 9 sides.
⠀

B is the correct answer, -1.
Isolate the variable by dividing each side by factors that don't contain the variable.
K, remember
(ab)/(cd)=(a/c)(b/d) or whatever
also

and

and
![x^ \frac{m}{n}= \sqrt[n]{x^m}](https://tex.z-dn.net/?f=x%5E%20%5Cfrac%7Bm%7D%7Bn%7D%3D%20%5Csqrt%5Bn%5D%7Bx%5Em%7D%20%20)
and

and

and
(a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)

Answer:
x = 10.8
y = 11.2
Step-by-step explanation:
AB : AP = AC : AQ
5 :(5+9) = 6 : (6+x)
5: 14 = 6 :(6+x)
5(6+x) = 14*6
30 + 5x = 84
5x = 54
x = 10.8
AB : AP = BC :PQ
5 :14 = 4 : y
5y = 14*4
y = 11.2
Answer:
the first is true
