C is the answer radical 77/22
Answer:
Step-by-step explanation:
The interior angle of any polygon is:
(n-2)180
(n-2)180=3240
Dividing both sides by 180
n-2=3240/180
n-2=18
n=18+2
n=20
One interior angle is then 3240/20=162 (degrees)
Answer:

The axis of symmetry is the x- axis of the vetex.
Answer:
3
Step-by-step explanation:
If y varies directly with x, we have:
When y=12, x=4
Substituting these values into the equation
12=4k
k=12/4
k=3
The constant of proportionality is 3.
