Erik and Nita are playing a numers game. If the difference of their two numbers is less than 10 then Erik wins. If the differece between their two numbers is greater than 10 then Nita wins. The numbers to choose from are zero to twenty. What is the range of numbers that will win the game for your player? (Erik) If your player is Erik, assume that Nita chooses 7. Remember that Erik and Nita can only use numbers from zero to twenty)

The range of numbers that will win the game for your player is .

Step-by-step explanation:

We are given that Erik and Nita are playing a numbers game. If the difference between their two numbers is less than 10 then Erik wins. If the difference between their two numbers is greater than 10 then Nita wins.

The numbers to choose from are zero to twenty.

Our player's name is Erik and we have to find the range of numbers that will win the game for Erik.

Given that Nita chooses 7.

Since we know that if the difference between the numbers chosen by Erik and Nita is less than 10 then Erik wins, so the inequality represented taking into account that Nita chooses 7 is given by;

,  where x = number chosen by Erik, i.e.

Further solving the above equation we get;

But keeping in mind the fact that Erik and Nita can choose numbers between 0 and 20 (inclusive) only.

SO, the required range of numbers that can win Erik the game is given by = .

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
