Answer: Your answer is X=6
Step-by-step explanation:
10/3 = 20/x
Determine the defined range
10/3 20/x, x=0
Cross-multiply
10x = 60
Divide both sides by 10
x=6,x=0
Check if the solution is in the defined range
SOLUTION x=6

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
After you've calculated a least common multiple, always check to be sure your answer can be divided evenly by both numbers. Find the LCM of these sets of numbers. Multiply each factor the greatest number of times it occurs in any of the numbers. 9 has two 3's, and 21 has one 7, so we multiply 3 two times, and 7 once.
