Answer:
Step-by-step explanation:
YES IS THE ANSWER BECAUSE X=9
AND 11+3=87
Dodecagon is a plane figure with 12 sides. To find the sum of angles of a dodecagon, we have to use the formula of sum of angles of a polygon with n sides, which is
S= (n-2)180
For Dodecagon , n=12. Therefore on substituting 12 for n , we will get
S= (12-2)180 =10*180 = 1800 degree .
SO the sum of angle measures of a dodecagon is 1800 degree .
Answer:
2
Step-by-step explanation:
4 1/4 bags of flour multiplied by 2 is 8 2/4 and that's equivalent to 8 1/2
Solve for x
2x+3y=9
2x=9-3y
2x/2 = 9-3y/2
X=9-3y/2
Solve for Y
2x+3y=9
3y=9-2x
3y/3 = 9-2x/3
Y=9-2x/3
Y=-2x/3 + 3
