The equation for this is (n-2) x 180
Replace n with the number of sides:
a. 9: (9-2) x 180 = 7 x 180 = 1,260
b. 19: (19-2) x 180 = 17 x 180 = 3,060
Answer:
x = 3
Step-by-step explanation:
2x + 8 = 14
2x = 6
x = 3
Step-by-step explanation:
R=2m
A=πr²
A = 3.142*2*2
=12.568 m2
That's for the equation I got from the picture
The answer is that the ratio of a to c is 9/5
