Answer:
x=2, y=16
Step-by-step explanation:
x+y=18
y=8x
x+8x=18
x=2
y=16
 
        
                    
             
        
        
        
Answer:
C = 69.1 ft
Step-by-step explanation:
The circumference is given by
C = 2*pi*r
C = 2* 3.14 * 11
C =69.08
Round to the nearest tenth
C = 69.1 ft

Answer:
A: 65° B: 65° C: 125° D: 125°
Step-by-step explanation:
It is an equilateral(shown by the two dashes) and all angles in a triangle add up to 180°.
180-50 divided by 2 to give you A and B angles.
Then angled on a straight line add up to 180° so if you take angle A away from 180° you will get the answer to angle C. 
The same for angle D.
