Answer:
3
Step-by-step explanation:
Use the formula that states that the sum of the angles of an n-sided polygon is given by
S=(n−2)180
0
........(1)
Since we are given that the two angles are right angles and each of the remaining angles is 144
0
, therefore, the sum is:
S=90
0
+90
0
+(n−2)144
0
.........(2)
Therefore setting (2) equal to (1) we get
(n−2)180
0
=90
0
+90
0
+(n−2)144
0
⇒(n−2)180
0
−(n−2)144
0
=180
0
⇒(n−2)(180
0
−144
0
)=180
0
⇒(n−2)(36
0
)=180
0
⇒n−2=
36
180
⇒n−2=5
⇒n=5+2=7
Hence, the polygon has 7 sides.
Answer:

Step-by-step explanation:
All three angles in an equilateral triangle are equivalent, and they sum up to 180°, so each angle measures 60°:
60° = [8x - 44]°
+ 44° + 44°
____________
![\displaystyle \frac{104°}{8} = \frac{[8x]°}{8} \\ \\ 13° = x](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B104%C2%B0%7D%7B8%7D%20%3D%20%5Cfrac%7B%5B8x%5D%C2%B0%7D%7B8%7D%20%5C%5C%20%5C%5C%2013%C2%B0%20%3D%20x)
