When two triangles are congruent, their corresponding sides and angles are equivalent. Since ∠W and ∠S are two corresponding angles, their measures will be equal to each other. We're given that m∠W = 8n + 10 and m∠S = 10n - 24, so we can set up an equality between the two:

8n + 10 = 10n - 24

Moving the 8n over to the right side by subtraction and the 24 over to the left side by addition, we get

10 + 24 = 10n - 8n

34 = 2n

and dividing both sides by 2 to get n by itself gives us

17 = n

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
